User-defined character command is used to draw characters of
your own design. Each segment of character is drawn according
to three parameter values as follows:
Pen control parameter +99 = pen down
Pen control parameter -99 = pen up
X-Increment specifies number of character grid units that pen
will move horizontally. Positive value moves pen to right and
negative value moves it to left. Increment value can range
from -98 thru +98 grid units .
Y-Increment specifies number of character grid units that pen
will move vertically. Positive value moves pen up and
negative value moves it down. Increment value can range from
-98 thru +98 grid units.
Character grid units are scaled by current size statement.
Each character block contains 6 horizontal grid units and 16
v e r t i c a l g r i d u n i t s .
Each character starts from character block origin point. When
character is completed, LF is sent automatically by WRITE
statement at end of string of characters, returns pen to next
c h a r a c t e r b l o c k o r i g i n ( s i x g r i d u n i t s f r o m i n i t i a l s t a r t i ng
