Download: quant12.xpl

Code:
  proc(j) = factorial(x) ; defines a procedure named "factorial"
    j = 1                ; defines the variable j as 1
    do                   ; opens the do loop
      j = j *x           ; computes j as the product of j and x  
      x = x -1           ; reduces x by 1
    until (x < 2)        ; if the condition is not fulfilled, 
                         ;    the loop will be run again
  endp                   ; end of the procedure
;
  factorial(5)      ; runs the procedure with value 5
