A function "plotter" in COBOL for z/OS mainframes.SYSIN should be a single record in form (for example)150 150 +1.000E-01 +0.000E-00where first two are maximum rows and columns of output dataset, and the rest are coefficients of a linear function that X is first passed thru (it normally goes from 1 to maxrows).Output dataset has name PLOTOUT.
