Graphics Functions

Eight-Pin Graphics Modes

All 8-pin graphics functions require parameters, n1 and n2, which represent the
length of the graphics string that follows the Select Graphics Mode command,
and are calculated as follows (assuming a temporary variable n):
n = total number of graphics dots needed for the graphic string
n2 = integer of (n divided by 256)
n1 = remainder of the n2 calculation
The simplest calculation, is to divide n (total number of dots needed for the
graphics string) by 256. Then 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.

Select Graphics Mode

The graphic mode, represented by the variable m (Table 3-4, Graphics Modes) is
enabled. The total number of dot columns to be printed is represented by n1 and
n2 (see parameter descriptions above). Any graphic string that exceeds the
length of the print line is discarded.
