I am doing a refresh of a test environment and need to recompile an LF
that is pointing to production.
I do a DSPFD to an *OUTFILE and then read that outfile looking for an
LF where the LF library is not the same as the "based on" library.
I do a CRTLF but it fails because the LF already exists.
If I delete the LF first then I can't run the routine again because
that LF won't be in the DSPFD file any more.
How do I get around this?
