nl and n2 represent the set of ASCII codes that define how many columns of graphics to print on a line. If you want to print “x” number of columns of graphics on a line, then:
nl is the remainder of x/256, and n2 is the quotient of x/256
Note: For those of you who are
nl = x
MODULO 256, and n2 = INTEGER of xl256
What does all this mean to the rest of us? The following table might help.
