You can instruct the assembler to pre-execute one of the SET directives using the following option:
--predefine "directive"
You must enclose directiveGBLL, GBLS, or GBLA directive to define the variable before setting its value.
The variable name is case-sensitive.
Note
The command line interface of your system might require you to enter special character combinations, such as \”, to include strings in directive--via to include a file--predefine argument. The command line interface does not alter arguments from --via files.
