XYPLOT is a one page subroutine which scales, offsets, and
simultaneously plots two integer arrays from any two data
fields, using the D/A converter and a conventional x-y re-
corder. Incorporation of a programmed pen lift makes available
to those users having the necessary additional hardware a point
plot capability, selectable by properly setting bit zero of the
variable PENFLG in the calling sequence. Loading of the
additional 41 (octal) memory location program GENX, and
setting of bit one of PENFLG allows a y-data array to be
plotted versus locally generated, equispaced x-data, with the
spacing interval user specified.
