Set alternate command selects normal alternate set as
character set to be used for all labeling statements ( l b l ,
p t y p , xax, a n d y a x ) . T h i s command should be executed prior to
executing labeling statement whenever alternate character set
is to be used.

User-defined character command is used to draw characters of

to three parameter values as follows:
Pen Control Parameter +99 = Pen Down
P e n Control Parameter -99 = Pen Up
X-Increment specifies number of character grid units that pen
will move horizontally.
P o s i t i v e 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.
P o s i t i v e 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 as
s h o w n on the following page.
E a c h character block contains 6
horizontal grid units and 16 vertical grid units.
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
character block origin (six grid units from initial starting
point).
NOTE
This may not be a valid starting point if new charac-
ter was larger than normal character. A plt, iplot
or cplot statement may be needed to properly posi-
tion pen for next character, if any, to be lettered.
