SUBTTL QUM driver -- Daisy-wheel printers
; These routines drive the QUME, XEROX, DIABLO, GENCOM, or AJ830
; hard-copy terminals. Plotting is done in 1/48 inch increments
; vertically and 1/60 inch increments horizontally. The "pen" is the
; period character, struck so as to make a "continuous" line.

GENCOM TRUE PLOT mode
In TRUE PLOT mode, the characters 0 through ? set the quadrant for
movement, and whether to move in single or double increments.
single down 2 ! single down 3
single up 6 ! single up 7
double down : ! double down ;
double up .gt. ! double up ?
----------------+-----------------
single down 1 ! single down 0
single up 5 ! single up 4
double down 9 ! double down 8
double up = ! double up .lt.
Alphabetical characters @ through DEL move in TRUE PLOT mode. The
low order 3 bits specify the Y increments, the next 3 bits specify the X
increment.
