; loads the library graphic
library ("graphic")
; generate a dataset with 160 observations
t = (normal(25)-8)|(normal(25)+8)|normal(100)|(normal(10)+25)
; generate a qq-plot to compare t with a normal distribution
bp = grqqn (t)
; create a dispplay for plotting
d = createdisplay (1,1)
; plot the qq-plot
show (d, 1, 1, bp)
