Variables not utilized in NC code during code generation are stored as user comment. The
term "user comment" refers to all information required to recompile codes. User comment must
not be altered.
Note
The block consisting of NC code and user comment can be recompiled only if it starts at the
beginning of a line.
Examples:
The programm contains the following NC code:
DEF VAR1=(I//101)
OUTPUT(CODE1)
"X" VAR1 " Y200"
"X" VAR1 " Y0"
END_OUTPUT
The following code is then stored in the parts program:
;NCG#TestGC#\cus.dir\aeditor.com#CODE1#1#3#
X101 Y200
X101 Y0
;#END#
The Editor reads the following during recompilation:
X101 Y200
X222 Y0
The following value is displayed for VAR1 in the input dialog: VAR1 = 222
