Weird problem with service program binding

[James Lampert <jamesl@xxxxxxxxxxxxxxxxx>]

We have a program that is bound to the ZLIB service program. If we 
specify the library for ZLIB on the CRTPGM, then a DSPPGM on it shows 
that it's bound to ZLIB in that library, as expected.

Likewise, I ran a test CRTPGM, binding the program to ZLIB in *LIBL, 
both with and without having a copy of ZLIB in the target library, and 
in both cases, a DSPPGM on the resulting program showed that it was 
bound to ZLIB in *LIBL.

Yet we recently created another program, explicitly bound to *LIBL/ZLIB 
in the CRTPGM, and yet a DSPPGM on it shows it bound to ZLIB in a 
specific library, and we can't explain why.

The only thing that might have been different is that *possibly* the 
CRTPGM (called from within a CL program) may have initially failed to 
find the service program, and then been given a RETRY response after the 
service program was copied into the target library. Or the program may 
have been regenerated since then. (I'm not sure; I wasn't the one who 
did it.)
