File open fails because of a level check error -- can I catch this, and find out where it tried to open the file?

We have a situation in which an RPG program is checking the library on an open file, to make sure it's open in the right library. If it isn't, it closes out the "wrong" instance of the file, shells out commands to remove the "wrong" library from the *LIBL and add the "right" one, then reopens the file in the "right" library.

In short, to pseudocode, with LibraryWeGot derived from open feedback on a file:

WHILE LibraryWeWant <> LibraryWeGot
close all the files
shell out "RMVLIBLE " + LibraryWeGot
shell out "ADDLIBLE " + LibraryWeWant + "*LAST"
reopen all the files

(And EXTFILE clauses on the F-specs are not an option here, for reasons I'd rather not go into.)

At any rate, I just discovered a loophole: if the file on which we're getting the open feedback has a level check issue, the exception stops us before we reach the block that checks to see if we're in the right library.

Assuming I catch the exception, is there an easy way to find out what "LibraryWeGot" is?
