The simplest calculation is to divide
graphics string) by 256. Then
remainder. If you require less than 256 dots (columns), then
number of dots and
n2
Enables the specified graphics mode. Any graphic string that exceeds the length of the
print line is discarded.
m is the graphics mode to be selected:
•
0: Single-density
•
1: Low speed double-density
•
2: High-speed double density (cannot print adjacent dots in a given row)
•
3: Low-speed quadruple density (cannot print adjacent dots in a given row)
•
4: CRT 1
•
5: Single-density plotter
•
6: CRT II
•
7: Double-density plotter (cannot print adjacent dots in a given row)
n1 and n2 are calculated based on the temporary variable n, which equals the total
number of dots needed for the graphics string.
To calculate n1 and n2, divide n by 256. n2 is the quotient (the whole number) and n1 is
the remainder.
If you require less than 256 dots (columns), then n1 indicates the number of dots and
n2 is set to zero.

Changes graphic modes.
s is one of the K, I, Y, or Z characters.
n is one of the graphics modes:
•
0: Single-density (60 dots per inch, 480 dots per 8-inch line)
•
1: Low-speed double-density (120/960)
•
2: High-speed double-density
(cannot print adjacent dots in a given row, 120/960)
•
3: Low-speed quadruple density (240/1920)
•
4: CRT I (80/640)
•
5: Single-density plotter (72/576)
•
6: CRT II (90/720)
•
7: Double-density plotter
(cannot print adjacent dots in a given row, 144/1152)
