OUTPUT 718; "D2;"
The above program line selects display size 2 for the CRT display of the analyzer.
A single character space (see above) has an absolute outside limit of 16 (x) by 32 (y) units in any display size. A
character position is referenced from the lower left corner of each character space. The actual "character bound-
ary" is designated by the ascender and descender limits.
From the center of the character space, x may be changed as many as + 7 units and y by as many as + 15 units
before the text begins at the next x and y character. If a plot absolute statement calls a position anywhere in the
character space, the character will be placed within the "character boundary." If two characters are labeled into the
same character space, they will be superimposed over one another.
Example :
To begin labeling text 6 characters up from the bottom and 24 characters from the left (in any display size), the plot
absolute vector values are calculated for the center of the character location as follows:
x = (character spaces) (16) - 8
= (24) (16) - 8 = 376
y = (character spaces) (32) - 16
= (6) (32) - 16 = 176
