6.2.8 Example Version management with OUTPUT blocks
Overview
Additional variables can be added to existing dialogs when expanding the user interface. A
version identifier in parentheses is appended to the additional variables in the definition
following the variable name: (0 = Original, is not written), 1 = Version 1, 2 = Version 2, etc.
Example
DEF var100=(R//1)
DEF var101(1)=(S//"Hello")
When writing the OUTPUT block, you can specify which variables are written, with reference
to a particular version identifier.
Example
OUTPUT(NC1)
OUTPUT(NC1,1)
The OUTPUT block for the original version does not need a version identifier, however you
can specify it with 0. OUTPUT(NC1) is equivalent to OUTPUT(NC1,0). Version identifier n in
the OUTPUT block includes all variables of the originals 0, 1, 2, ... up to and including n.
Programming with version identifier
//M(XXX)
DEF var100=(R//1)
DEF var101=(S//"Hello")
DEF TMP
VS8=("GC")
PRESS(VS8)
END_PRESS
OUTPUT(NC1)
var100",,"var101
END_OUTPUT
