Chapter 8
Lines 80 and 90 are straight out of the HIRES INSTRUCTIONS program
listing. They load the screen dump routine without leaving the BASIC program.
As indicated in the HIRES instructions, we use the machine language routine
named EPSON.HIRES.OBJ (Line 90), and
where:
A = PAGE (O=PG.l, l=PG.2)
B = SIZE (O=SMALL, l=LARGE)
C = PICTURE (O=REG., l=INVERSE)
D = PRINTER SLOT (1 TO 7)
Therefore, our line 100 calls the routine to print the picture with:
Page 1 (Low) of memory,
Small size,
Regular picture, and
Printer slot # 1.
Change the USR statement in line 100 to suit your printing desires.
