Answer Wiki:
Without a whole lot of work, you cannot change FILENAME.
But, if you do not specify the LIBRARy, it will use *LIBL.
I'd be interested to know why you would want to do this.
It seems like it could cause a potential problem down the line,

CharlieBrown,
In a Change Management Environment when Promoting either the copybook and/or the programs from a Developers Library up to Test and/or Production, you would want the Libraries to change dynamically based on the library list.
Hope this helps,

I should have mentioned that.
We use MKS so that happens all the time.

When do you want to change it?
You can change it at run-time by using condition names in the DEFINE() parameter and coding your /COPY members with Conditional Compilation Directives. You can code your /COPY member to supply different values that depend what you supply in the DEFINE() parameter.
In your case you could have one /COPY member that would supply either a nested /COPY statement for LIBRARYA or another one for LIBRARYB. By nesting /COPY statements and choosing different ones under different conditions, you can get any final result you need.
But that has to happen at compile-time.
There is no way to affect a /COPY statement at any other time.
