@24 ? delete history
Enter 'Y' to delete all L# items and restart the session at L1.
Enter 'N' if you wish to SAVE any L# items first.
@25 help display
     The 'DISPLAY' command is used to view various types of saved
and current-session information.  To use this command, enter
'DISPLAY' and the name of the item to be displayed.  The system
will display the item online.

     For more information about the DISPLAY command, enter one
of the following HELP commands at any arrow prompt (=>).

=> HELP DISPLAY ACC ------- To see the record for a specific
                            Accession Number in a file.

=> HELP DISPLAY HISTORY --- To see the commands used in this
                            session.

@26 help search
The 'SEARCH' command is used to execute a search in the current
file.  To use this command, enter 'SEARCH' and a query name or a
logic expression.  The system will create an L-numbered answer
set containing the results of the search.

A logic expression (profile) consists of L-numbers, E-numbers,
text or numeric terms and/or saved query names, joined by Boolean
operators ('AND', 'OR', 'NOT') and/or by appropriate proximity
operators or by numeric operators (e.g., =, >, < ) in numeric
expressions. The order of precedence for the execution
of operators is (highest first) numeric operators, (W) and
(A) at the same level, (S), (P), (L), 'AND' and 'NOT' at the
same level, 'OR'.  Parentheses can be used to modify this
order.

If a saved name appears in a search, the full name must be
entered, including /Q.

Examples: => SEARCH L3 AND HEDGE/Q NOT SULFUR/Q
          => SEARCH PYRAZ/Q

Saved answer sets profiles must have L-numbers, obtained
by using the ACTIVATE command, before they can be used in the
SEARCH command.  The L-number, not the saved name, is used in the
SEARCH command.

For more information on logical operators, enter 'HELP
OPERATORS'.  Information on truncation of terms can be
reviewed by entering 'HELP TRUNCATION'.  For an explanation
of using numeric terms in a search, enter 'HELP NUMERIC'.
@27 help file
The 'FILE' command is used to select the file (database) for search,
display, and printing.  To use this command, enter 'FILE' and the name
of the file.  Subsequent SEARCH, DISPLAY, PRINT, and ACTIVATE commands
will be executed in this file until the next FILE command.

When you log in, you are automatically in the HOME file.  Use
the FILE command to change to another file.  Enter 'HELP FILE
NAMES' at an arrow prompt (=>) for a list of the files that are
available.  For general information on the current file, enter
'HELP CONTENT'.
@28 help query
The 'QUERY' command is used to build a search profile (query)
without executing a search.  To use this command, enter 'QUERY'
and a logic expression.  The system will assign an L-number to
the query.

A logic expression (profile) consists of L-numbers, E-numbers,
text or nemeric terms, and/or saved query names, joined by the
appropriate Boolean, numeric, or proximity operators. The order
of precedence for the execution of operators is (highest first)
numeric operators, (W) and (A) at the same level, (S), (P), (L),
'AND' and 'NOT' at the same level, 'OR'.  Parentheses can be used
to modify this order.

If a saved name appears in a query, the full name must be
entered, including /Q.

Example: => QUERY L3 AND HEDGE/Q NOT SULFUR/Q

Saved answer sets L-numbers, obtained by using the ACTIVATE command,
before they can be used in the QUERY command.  The L-number, not the
saved name, is used in the search profile.

For more information on logical operators, enter 'HELP OPERATORS'
at an arrow prompt (=>).
@29 help help
     The 'HELP' command is used to view explanations of
commands, formats, etc., at your terminal.  To use this
command, enter 'HELP' and the name of the item you want
explained.  The system will display an explanation of how to
use the item.

Example: => HELP DISPLAY  (For help with the DISPLAY command).

     For a list of commands, enter 'HELP COMMANDS'.  For a list
of online explanations, enter 'HELP MESSAGES'.

     Help is also available at any prompt, and after any error
message.  Enter 'HELP' or '?' at a prompt to see an explanation
of the options.  After an error message, enter 'HELP' or '?' at
the next prompt and you will receive a more detailed
explanation of the error and how to correct it.
@30 help select
     The 'SELECT' command is used to create E-numbered lists
that can be used for searching from display records. To use this
command, enter 'SELECT', the L-number of the answer set contai-
ning display records you want to SELECT, the code for the display
field, and the number(s) of the answers. You must be in the same
file in which the set was created.

     The result is an E-numbered list which looks much like an
EXPAND list. It contains all the terms that were in the display
field for the answers you specified. The terms are parsed, a '/'
and the display field code is appended to them, the number of
occurences in the selected fields is counted, and the terms are
ordered from most frequent to least frequent. When the process is
complete, a message is displayed telling the range of E-numbers
created.

Examples:
            => SELECT L6 AU 3,5,7-8,25
            E1-E12 ASSIGNED

            => SELECT L21 TI 1-20
            E13-E93 ASSIGNED

Unlike EXPAND commands, successive SELECT commands add to the end
of previous SELECT lists. If you exceed the maximum E-number, E250,
you will receive a message giving the number of the last answer
that was completely processed. You can pick the terms you want,
delete the list using 'DELETE SELECT', and then use SELECT again,
starting with the next answer.

    To see a list of the valid field codes for the SELECT command
in the current file, enter 'HELP DFIELDS' at an arrow prompt (=>).

    After the list has been created, you may wish to display it.
Use 'DISPLAY SELECT' to look at the list. Enter 'HELP DISPLAY
SELECT' for information. If you wish to change the field code, use
the EDIT command. Enter 'HELP EDIT' to find out how to use the
EDIT command.
@31 help save
The 'SAVE' command is used to save an L-numbered query or answer
set for use in a future session.  To use this command, enter
'SAVE', the L# of the item to be saved, and the name to be assigned
to the item.  A copy of the L-numbered item will be saved under the
name that you assigned.  To SAVE an answer set, you must be in
the same file that the answer set was created in.

The name that you choose must:

   1. Begin with a letter,
   2. Have 1-8 characters,
   3. Contain only letters (A-Z) and numbers (0-9),
   4. End with /Q (for a query, structure, or screen set)
      or end with /A (for an answer set),
   5. Not already be in use as a saved name, and
   6. Not be: END, SAV, SAVE, SAVED, or an L-number.

     To SAVE an item temporarily, enter the keyword TEMP on
the same line as SAVE. Items saved with the TEMP option are
deleted at the end of each week.

     If you wish to enter a short description of the saved
item, enter the keyword TITLE on the same line as SAVE.  You
will be prompted to enter a title, which will then appear each
time you DISPLAY or ACTIVATE the saved item.

Example:

=> SAVE L34 LUMICHROME/A TITLE
ENTER TITLE OR (NONE): CHROMATIC STUDY FOR DR. A. JONES.
ANSWER SET 'L34' HAS BEEN SAVED AS 'LUMICHROME/A'
@32 help activate
The 'ACTIVATE' command is used to assign L-numbers to
a saved query or answer set.  To use this command enter
'ACTIVATE' and the name of the saved item.
The system will assign an L-number(s) to the query or answer set.
These L-numbers can be used in subsequent QUERY,
SEARCH, DISPLAY, or PRINT commands.

An answerset can be activated only in the same file in which it
was created.  The name of a saved query must end in /Q.  The name
of a saved answer set must end in /A.

Examples:  => ACTIVATE PYRAZ/Q   (Activate a saved query)
           => ACTIVATE BORIC/A   (Activate a saved answer set)

A saved query must be activated before its definition
can be displayed, but it can be used directly in a
SEARCH or QUERY command without activation.  A saved
answer set must be activated before answers can be
displayed or printed, and before it can be used as a
search term in another file (file crossover).
@33 help set
The 'SET' command is used to specify changes from the default
terminal and session parameters, such as terminal padding and the
level of postings detail displayed with nested search
statements.
Only one of these parameters can be changed in a single SET
command.  Parameters are SET only for the current
session; they are not retained when you log off.

For details on the function of SET, enter one of the following
at an arrow prompt (=>).

HELP SET AUHELP ----------- automatically display of the second level help
HELP SET AUTOSEARCH ------- assume SEARCH command, missing valid a command
HELP SET MENU ------------- switch Messenger command menu on/off
HELP SET PRINTER ---------- switch printer on/off
HELP SET RELATION --------- switch relationship function (+ALL) on/off
HELP SET SCRIPT ----------- switch session script on/off

To get a list of the current values of the parameters, enter 'DISPLAY SET'
at an arrow prompt (=>).
@34 help news
     The 'NEWS' command is used to display current information
about the system.  Enter 'NEWS' at an arrow prompt (=>), and
a table of contents will be displayed. Enter 'NEWS', followed
by the number or name of the item you are interested in, at
an arrow prompt (=>) to see detailed information. To get information
on the latest updates and other news about the current file, enter
'NEWS FILE'.

@37 help delete
The DELETE command is used to remove various items stored by the
system.

To delete an individual L#, a range of L#'s, or all L#'s, enter the L#

@100 ? command stacking
You can stack several commands at a single arrow
prompt (=>) by separating the command steps with a
semicolon.  For example, a search for records containing
two terms is followed by a display of the first two answers
in the ALL format:

=> S IMMUNOASSAY AND RADIO?; D 1-2 ALL

Spaces around the semicolon are not critical.  A maximum
of 200 characters is permitted at a single arrow.  (The
maximum number of characters in a search statement is 200.)
The FILE command cannot be stacked with other commands.
@101 ? edit
     The EDIT command is used to change field codes, or make
other modifications to terms in lists of E-numbers, usually
from the SELECT command.  This is sometimes necessary
because search field codes are not always the same as the
display field codes, which are added to terms by the SELECT
command.  To use the command, enter 'EDIT', the E-number or
range of E-numbers to be modified, the character string to
be replaced, enclosed in quotes, and the new character
string, also in quotes.  For example, if you SELECTed titles
(TI display field) and wanted to search on the resulting
terms in the Basic Index, you could enter the following
(assuming the list contained 40 E-numbers):

        => EDIT E1-E40 "/TI" "/BI"

Every occurrence of the old character string will be replaced,
so including the '/' is a good idea.  If no new or replacement
character string is entered, the old character string will be
removed.

     Use 'DISPLAY SELECT' to redisplay the E-numbers after you
EDIT them, to make sure that your EDIT had the desired effect.
For more information on displaying E-numbers, enter 'HELP
DISPLAY SELECT' at an arrow prompt (=>).  To find out how the
SELECT command works, enter 'HELP SELECT'.
@102 ? expand
     The 'EXPAND' command is used to look at the index in files
which have an index.  To use this command, enter 'EXPAND' and
the term you are EXPANDing at an arrow prompt (=>).  If you wish
to see terms from a particular field or fields , enter up to 3
field qualifiers, separated by commas, after the term.
Otherwise, the terms will be from the default expand fields(s),
which are file dependent.  The single letter 'E' can be used for
the expert version of EXPAND.

     You may specify a total number of terms to be displayed in
the range 5-25.  If you do not specify, 12 terms will be
displayed.  The term you enter is always the third term in the
list, even if it is absent from the index.

     EXAMPLES: => EXPAND ATOM
               => EXPAND HEXANE/CN
               => EXPAND PHARMACOLOGY 20
               => EXPAND LAWSON,C./AU 15

After the first set of terms has been displayed, you can specify that
the listing of inverted index terms be continued by entering 'E'.
By several continued EXPANDs, up to 250 terms can be displayed.
If you wish to start a new EXPAND list, enter EXPAND (or E) followed
by a new term to be expanded.  EXPAND lists can only continue in the
same file.  If you change files you must start a new EXPAND list.

     If left truncation is allowed in any fields in the current
file, you may enter 'EXPAND LEFT' and the term you want to
see.  The terms in the resulting display will be in the order
that they occur in the left index, but will not be fragmented
to show the embedded stem.  Enter 'HELP SFIELDS' at an arrow
prompt (=>) for information on the search fields in the current
file.

     The terms in the EXPAND listing are lableled with E#'s which
can be entered instead of the term itself in subsequent SEARCH
commands.  E# ranges can also be used in the SEARCH command.
For example, 'SEARCH E3-E5' is equivalent to 'SEARCH E3 OR E4 OR
E5'.
@103 ? display acc
     The 'DISPLAY ACC' command may be used to look at the
record for an accession number.  To use this command, enter
'DISPLAY ACC' followed by a list of one to twenty accession
numbers (separated by commas), and then the display format.
You must be in the correct file for the type of accession
number.

Example: => DISPLAY ACC 100, 345 BIB ABS

For a list of the display formats in the current file, enter
'HELP FORMAT' at an arrow prompt (=>).  For a list of accession
number formats, enter 'HELP ACCESSION'.
@104 ? display browse
     The 'DISPLAY BROWSE' command is used to view answers from an
L# answer set.  It is a convenient way to look at a series of
answers from a set without re-entering the DISPLAY command before
each display request.  To use the command, enter 'DISPLAY BROWSE'
and the L# of the answer set.  You will then be prompted for an
answer number or format.  The default, 'DIS', means "display the
next answer in the default format".  You may specify the answer
number(s) and display format if you wish.  After you have displayed
an answer in one format, you may enter the name of another format
to display the same document in a different format.  If you wish to
change the default format, enter an asterisk and the format you
want at the prompt (e.g., '*ALL').  After an answer number or range
is displayed, you will again be prompted for an answer number.
When you are done looking at answers, enter 'END' to return to the
arrow prompt (=>).

Example:

  => DISPLAY BROWSE L5

  ENTER (DIS), ANSWER NUMBERS, FORMAT, OR END:  5-8 ALL

  (Answers 5-8 are displayed in ALL format)

  ENTER (DIS), ANSWER NUMBERS, FORMAT, OR END: 12,18

  (Answers 12 and 18 are displayed in the default format)

  ENTER (DIS), ANSWER NUMBERS, FORMAT, OR END: ALL

  (Answer 18 redisplays in ALL format)

  ENTER (DIS), ANSWER NUMBERS, FORMAT, OR END: * BIB

  (Default format is changed to BIB)

  ENTER (DIS), ANSWER NUMBERS, FORMAT, OR END: END

=>

     Some files, especially those containing large documents,
have additional options.  These are moving forward and backward
inside a document by specifying F or B and a number indicating
how many fields forward or backward you wish to move, and
searching in the record for a character string.  To find out if
the file you are in has these options, enter a '?' at the 'ENTER
(DIS), ANSWER NUMBER(S), FORMAT, OR END:' prompt.  If these
features work in the current file, you will find them listed
among the options.

For a list of display formats in the current file, enter 'HELP
FORMAT' at an arrow prompt (=>).

     For another way to display answers from an L# answer set,
enter 'HELP DISPLAY L#'.

     Before answers from a saved (/A) answer set can be
displayed, they must be activated.  To do this, enter
'ACTIVATE' and the name of the saved answer set.  The system
will retrieve the answer set and will assign its query
L-numbers.  Enter 'DISPLAY BROWSE' and the final L-number to
display the answers.
@105 ? display cost
@106 ? display history
     The 'DISPLAY HISTORY' command is used to view a selected
list of the commands entered in the current session.  To use
this command, enter 'DISPLAY HISTORY' followed by 'ALL', or by
one L-number, or by a range of L-numbers, or by the first or
last L# in a range.

Examples:

=> DISPLAY HISTORY ALL
   (All commands in this session are displayed)

=> DISPLAY HISTORY L5
   (Only the command that created L5 is displayed)

=> DISPLAY HISTORY L8-L12
   (Only the commands that created L8 through L12 are displayed)

=> DISPLAY HISTORY L4-
   (The command used to create L4 and the commands used after
    creating L4 are displayed)

=> DISPLAY HISTORY -L15
   (The command used to create L15 and the commands used prior to
    creating L15 are displayed)
@107 ? display l#
The 'DISPLAY' command may be used to view answers from an
L# answer set.  To use the command, enter 'DISPLAY', the
L# of the answer set, the format (if different than the
default), and the answer number(s) or range you wish to see.

Example: => DISPLAY L3 ALL 2-5,7

(Answers 2-5 and 7 from answer set L3 are displayed in ALL
format)

After the answers have been displayed, the arrow prompt
(=>) will appear.  To display more answers, you must again
enter the DISPLAY command, followed by the L#, format,
and answer numbers.

For a list of display formats in the current file, enter
'HELP FORMAT' at an arrow prompt (=>).

For another way to display answers from an L# answer set,
enter 'HELP DISPLAY BROWSE'.

     Before answers from a saved (/A) answer set can be
displayed, they must be activated.  To do this, enter
'ACTIVATE' and the name of the saved answer set.  The system
will retrieve the answer set and will assign its query
L-numbers.  Enter 'DISPLAY' and the final L-number to display
the answers.
@108 ? display print
@109 ? display query
     The 'DISPLAY QUERY' command is used to look at the query
(search profile), structure, or screen set for an L-number in
the current session.  To use this command, enter 'DISPLAY
QUERY' and the L# of the query.

     For text (non-structure) queries, all search terms
associated with the L#, including the definitions for any
referenced L#'s, will be displayed.  The number of postings will
be shown for L#'s created by the SEARCH command.  To see the
definitiontsaved (/Q) text query, ACTIVATE it.  All search
terms will be displayed in the ACTIVATE step.
@110 ? display saved
     The 'DISPLAY SAVED' command is used to list the names of
saved queries and answer sets.  To use this command, enter one
of the following at an arrow prompt (=>):

=> DISPLAY SAVED/Q --- To view a list of all saved query names.

=> DISPLAY SAVED/A --- To view a list of all saved answer set
                        names.
=> DISPLAY SAVED ----- To view a list of all saved query and
                        answer set names.

To display information about an individual saved item, enter
DISPLAY and the name of the item with the appropriate suffix.
@111 ? display select
     To see the list of E-numbered terms created by the SELECT
command, enter 'DISPLAY SELECT' followed by 'ALL', one
E-number, a range of E-numbers, or the first or last E-number
in a range.

Examples:

=> DISPLAY SELECT ALL
   (All E-numbers are displayed)

=> DISPLAY SELECT E10
   (E10 is displayed)

=> DISPLAY SELECT E15-E25
   (E15 through E25 are displayed)

=> DISPLAY SELECT E100-
   (E-numbers from E100 to the end of the list are displayed)

=> DISPLAY SELECT -E30
   (All E-numbers up to E30 are displayed)
@112 ? print acc
     The 'PRINT ACC' command may be used to print the record for
a particular accession number in a file.  To use the command,
enter 'PRINT ACC' followed by a list of one to twenty accession
numbers.  If you want to PRINT more than twenty records, hit
the 'Return' or 'Enter' key, and you will be prompted for
more accession numbers.  You will be prompted for the print
format.  The PRINTing of data associated with a particular
accession number can only be done in the file where that
number is valid, e.g., you must be in the CA file to PRINT
records for CA Abstract Numbers or in the MATH file to PRINT
records for Mathematics Abstracts abstract numbers.

     If you wish to add a short description of your print request
to be included on the query page of the offline prints, enter the
word TITLE on the same line as the command PRINT.  You will then be
prompted to enter a title.  You may enter up to five lines of 40
characters each.

     If you want the offline print mailed to an address
different from your permanent mailing address, enter
Y at the prompt 'CHANGE MAILING ADDRESS?' You will be prompted
to enter a new address.  This address will be used for offline
print and document orders for the rest of the session, unless
you change it again in the PRINT or ORDER command.  The address
reverts to your permanent mailing address when you log off.

     If you do not want the mailing address to be displayed,
enter 'NOA' on the same line as the PRINT command.

     For a list of print formats in the current file, enter
'HELP FORMAT' at an arrow prompt (=>).  Enter 'HELP ACCESSION'
for a list of accession number formats in the current file.
@113 ? print l#
     The 'PRINT' command may be used to have an answer set
(search results) printed offline and mailed to you.  To use
this command, enter 'PRINT' followed by the L# of the answer
set.  You will then be prompted for the print format, and the
answer numbers of the answers to be printed.

     If you wish to add a short description of your print request
to be included on the query page of the offline prints, enter the
word TITLE on the same line as the command PRINT.  You will then be
prompted to enter a title.  You may enter up to five lines of 40
characters each.

     If you want the search results mailed to an address
different from your permanent mailing address, enter
'Y' at the prompt 'CHANGE MAILING ADDRESS?' You will be prompted
to enter a new address.  This address will be used for offline
print and document orders for the rest of the session, unless
you change it again in the PRINT or ORDER command.  The address
reverts to your permanent mailing address when you log off.

     If you do not want the mailing address to be displayed,
enter 'NOA' on the same line as the PRINT command.

     For a list of print formats for answers in the current
file, enter 'HELP FORMAT' at an arrow prompt (=>).
@114 ? set cost
@115 ? set graphics
@116 ? set headings
@117 ? set highlighting
If you do not wish to have het terms highlighted in files where this
feature is available, enter 'SET HIGHLIGHTING OFF' at an arrow prompt
(=>) to suppress it.  If you want hit term highlighting in any file
where it is available, enter 'SET HIGHLIGHTING ON'.

Each file that has hit term highlighting will have a default value
for SET HIGHLIGHTING.  This will usually be ON, but can be OFF.  If
you enter a 'SET HIGHLIGHTING' command, this will take precedence
over any system default values.

To find out about hit term highlighting in the current file, enter
'HELP HIGHLIGHTING' at an arrow prompt (=>).
@118 ? linelength
@119 ? set padding
@120 ? set pagelength
   If you are working in page mode, 'SET PAGELENGTH' may be
used to change the maximum number of lines that will be displayed
before the message 'COPY AND CLEAR PAGE, PLEASE' appears.  It may
also be used to suppress the message and allow continuous
scrolling.

   To change the length of your screen display, enter 'SET
PAGELENGTH' and the number of lines (8-99) on your screen at an
arrow prompt (=>).  When you log in as a Type 1 or 2 terminal,
page length is set to 33 by default.  Many personal computers
have a screen length of 24 lines.

   To make the display scroll, enter 'SET PAGELENGTH
SCROLL'.  When you log in as a Type 3 terminal, pagelength is set
to SCROLL.  If you have logged in as a Type 3 and would like to
have the screen display stop every 24 line, enter SET PAGE 24.
Just enter a carriage return at the 'COPY AND CLEAR' message, and
the display will continue.
@121 ? set postings
   The postings detail level may be SET to 'ON', 'FULL', or
'OFF'.

   A value of 'ON' means that postings will be shown for
individual search terms, proximity expressions, and nested
profile references.  'ON' is the default; when you log in,
POSTINGS are set to 'ON'.

   'FULL' gives all of the postings values reported by 'ON'
plus postings for individual terms in nested profiles.

   For 'OFF', only the number of postings for the final
answer set will be given.
@122 ? set printer
If you want the actual session being printed on a printer,
enter 'SET PRINTER ON'. If you do not wish to print the session,
enter 'SET PRINTER OFF' at an arrow prompt (=>) to suppress it.
@123 ? set range
@124 ? set steps
     You may specify that all intermediate postings lines in
searches be assigned L#s by entering 'SET STEPS ON' at an arrow
prompt (=>).  If you no longer wish to have L#s assigned to the
intermediate postings, you can return to the default condition of
OFF by entering 'SET STEPS OFF' at an arrow prompt.

     Only 99 L-numbers can be created in an online session.  If
you use the STEPS ON option, you may reach this limit.  When this
happens, use the SAVE command to save any L-numbered answer sets
or queries that you want to continue using.  The use 'DELETE
HISTORY' to delete all L-numbers and restart your session at L1.
After you have restarted your session, ACTIVATE the items you
have saved, and they will again be available as L-numbers.

     You can also specify that L#s be assigned to intermediate
postings in the SEARCH command.  For information on this option,
enter 'HELP SEARCH STEPS' at the arrow prompt.
@125 ? search range
@126 ? search steps
To have L#s assigned to the intermediate postings of a SEARCH,
add the word 'STEPS' before or after the logic expression in the
SEARCH command.  For example,

=> SEARCH STEPS A AND (B OR C) NOT D
L1 (        1000)A
L2 (         200)B
L3 (         100)C
L4 (        2000)D
L5            10 A AND (B OR C) NOT D

The L#s assigned to the intermediate posting lines can be used
instead of the terms themselves in subsequent SEARCH or QUERY
commands. Answers can be DISPLAYed only from the L# answer sets
that are the end result of the SEARCH. If the number of postings
is in parentheses, the L# cannot be used for answer display.

For information on having L#s automatically assigned to all
intermediate postings lines, enter 'HELP SET STEPS' at an
arrow prompt (=>).
@127 ? operators
The following operators are available for use in searching:
'AND', 'OR', 'NOT', (W), (A), (P), (S), (L), and numeric
operators.  The order of precedence for the execution of
operators is (highest first): numeric operators, (W) and (A) at
the same level, (S), (P), (L), 'AND' and 'NOT' at the same
level, 'OR'.  Parentheses (nesting) can be used to alter the
order of execution.  For example, the expression

=> SEARCH A AND B OR C NOT D is equivalent to

=> SEARCH (A AND B) OR (C NOT D).

If the search logic required the set 'B OR C' to be combined
with set A by 'AND' logic and set D by 'NOT' logic, parentheses
would be required as shown below to produce the desired
results.

=> SEARCH A AND (B OR C) NOT D

For more information on the individual operators, enter 'HELP'
and one of the following at an arrow prompt (=>):  'NUMERIC',
'AND', 'OR', 'NOT', '(A)', '(W)', '(S)', '(P)', or '(L)'.  The
numeric, Boolean, and (A) and (W) word proximity operators work
the same in all files.  However, the function of the (S), (P),
and (L) operators depends on the data structure of the file you
are in.  Entering 'HELP (S)', 'HELP (P)', or 'HELP (L)' will
give information about how these operators work in the current
file.
@128 ? numeric
Several files have special fields with numeric
information.  Examples of these include dates in the
PHYS file and element counts in the REGISTRY file.
Numeric information can be searched as a single value,
a range of values, or for any value above or below a
particular value.  To search for a single value,
e.g., a carbon count of 5, enter either 5/C or
C=5.  To search for a range of values, e.g., 5-10
bromines, enter 5-10/BR or 5<=BR<=10.  Ranges entered
as, e.g., 5-10/BR, are always inclusive.  This
means that the endpoints are included in the search.
The '>' and '<' operators can also be used, e.g.,
UP>840501.  In the order of precedence, numeric
operators are executed before either proximity
or Boolean operators.

To find out what fields are numeric in the current file,
enter 'HELP SFIELDS' at an arrow prompt (=>).
@129 ? and
Combining two or more terms with the AND operator requires
that all the terms occur in the same document or record.
Use of the AND operator usually decreases the number of
answers that are retrieved.
@130 ? or
Combining a set of terms with the OR operator requires
that at least one term be present in a document or record
in order for it to be an answer.  Use of the OR operator
usually increases the number of answers that are retrieved.
@131 ? not
A search expression such as 'A NOT B' requires that
a document or record contain the term A but not the term B.
The NOT operator should be used cautiously.  A document
may contain information on both A and B, but 'NOT B'
would eliminate it from the answer set.
@132 ? (a)
The (A) operator is used to search for adjacent terms in
any order.  For example, 'SHALE(A)OIL' would retrieve
both OIL SHALE and SHALE OIL.  The (A) operator can also
be used to search for terms within a specified number of
words of each other, e.g.  'AIR(3A)POLLUTION'.
@133 ? (w)
The (W) operator is used to search for adjacent terms and implies
order, i.e., a search for POLYMERIZATION(W)CATALYST would not
retrieve document records where these two terms only occurred in
the reverse order.  The (W) operator can also be used to search
for terms within a specified number of words of each other.  For
example, 'SEARCH DENTAL(3W)ALLOY' would retrieve records
containing these terms with three or fewer intervening
words.

@139 help truncation
Three types of right truncation of a search term are available:

    the question mark, '?', indicating any number of characters,
         including zero, may occur to the right of this symbol,
         e.g., 'STEROID?' (retrieves such terms as STEROID,
         STEROIDS, and STEROIDAL);

    the hash mark, '#', indicating that either one or zero
         characters occur at the end of the search term, e.g.,
         'CASEIN#' (retrieves CASEIN and CASEINS);

    the exclamation mark, '!', indicating that exactly one
         character be present at the end of the word, e.g.,
         'AMOEBA!' (retrieves AMOEBAE as well as AMOEBAS).

Note that the '!' can also be used within a search term, e.g.,
'THERMOLYS!S' (retrieves THERMOLYSIS and THERMOLYSES).

Multiple occurrences of the '#' and the '!' are allowed.  All
symbols can be used in combinations.  Examples of search terms
containing more than one truncation symbol are:

    SULFON!TE?   (retrieves SULFONATE, SULFONATES, SULFONITE)
    PROPELL!NT#  (retrieves PROPELLANT, PROPELLENT, PROPELLANTS)
    ELECTROSTAT####  (retrieves ELECTROSTAT, ELECTROSTATIC)

INCONSISTENT NUMERIC RANGE EXPRESSION
@270
A single numeric search expression cannot contain both '>'
and '<' operators (for example, '11 > LD < 50' is not valid),
or a '>' or '<' operator and an '=' sign.  The lower limit
of a range must be less than the upper range limit (for
example, '50 < LD < 11' is not valid).

Examples of valid numeric search expressions:

      20 < LD < 50        and  50 > LD > 20
@271
The lower limit in a numeric range must be given
before the upper limit.  For example, '5-1/C' is
not valid.  The correct form is '1-5/C'.
@272
Numeric values may contain 1-8 significant figures.
If range notation is used, both the beginning and the
end of the range must be specified, e.g., '250-300/MW'.
Expressions such as '250-/MW' are not allowed.  To
search for values above or below a given number, use
the >, =>, < or <= operators, e.g., 'MW => 250'.  Text
terms cannot be used in numeric expressions.

The STN electronic mail service is available to all users by
entering the STNMAIL file.  This service allows users to send and
read mail messages, as well as to answer and forward these messages.
Messages may be created and edited online or uploaded from local
files.  Messages may be saved online in file folders or downloaded
to local files.  Structure, numeric, and text queries may be
included in messages and retrieved in searchable form using special
commands.  Saved queries and answer sets may also be included in
messages and retrieved as saved items by the recipient.  Information
about users in the public mail directory may be searched and
displayed online.  Personal mailing lists may be created to
facilitate sending messages to individuals or groups of users.

In order to use this electronic mail service, you must first
establish your mail address.  For information on the special
commands available for this service, enter one of the following at
an arrow prompt (=>):

HELP COMMANDS ----- For information on the commands available

To read your electronic mail messages, first use the FILE command to
switch to the STNMAIL file by entering "FILE STNMAIL" at an arrow
prompt (=>).  Then enter "READ" and one of the following options at
the next arrow prompt (=>):

MAIL --------- To process incoming messages placed in your mailbox
MAIL ALL ----- To display all the messages in your mailbox
MAIL NEW ----- To display all unread messages in your mailbox
FOLDER ------- To display a list of your existing folder names
FOLDER X ----- To process messages you saved in folder "X"
FOLDER X ALL - To display all the messages in folder "X"
NAMELIST ----- To display the names of your personal mailing lists
NAMELIST Y --- To display the mail IDs in namelist "Y"
PUBLIC ------- To search information in the public mail directory
               (display one-line format)
PUBLIC LONG -- To search information in the public mail directory
               (display long form, all available fields)

You may also select most of these options by entering "READ" at the
arrow prompt (=>).  The system will prompt you to select one of the
following four options:  MAIL, FOLDER, NAMELIST, or PUBLIC.  MAIL is
the default option and may be selected by entering "." at the colon

"HELP SET MAILID" at an arrow prompt (=>).  For information on
finding mailids in the public mail directory, enter "HELP READ
PUBLIC" at an arrow prompt (=>).

To send a message, first use the FILE command to switch to the
STNMAIL file by entering "FILE STNMAIL" at an arrow prompt (=>).
Then enter "SEND" at the next arrow prompt (=>).  The system
will first help you create the message "envelope" by asking for a
'TO' mailid.  The next 'CC' and 'SUBJECT' prompts are

provide this information.  For more information on how to respond to
any of these prompts, enter "HELP" or "?" at the colon (:)
prompt.  After you complete the "envelope", the system will prompt
you for a command to create and process your message.  The system
prompt lists four of these commands.

Example:
   => SEND
   TO (NONE): 2143C
   CC (NONE): .
   SUBJECT (NONE): .
   ENTER (WRITE), UPLOAD, VIEW, SEND, OR ?:

To see a list of all the message-creating commands, enter "HELP"
