Why not let the RPG open the file and grab the library from the INFDS?

dcl-ds fileDS;
libName char(10) Pos(93);
end-ds;

Works for me.

Not that you were actually asking this, but I'm pretty sure the answer
to "why not" is simply that people don't know about it; or they
forget, because it's not something they use often enough. This is much
neater and more elegant than the other alternatives presented so far.

Yes, if the object name is known in advance, if the object of
interest is a file, if there is only one or two files of interest, then I
agree that opening the file in RPG and using the information data
structure is just fine. But there are many reasons that is often
insufficient.

Sincerely,

Dave Clark
