Re: Find a CL program's library - While it is running

[John Earl <johnearl@xxxxxxxxxxx>]

Dave (and all),

Thanks for the samples and suggestions.

This problem defied some of the simpler solutions because the CL program in
question gets a qualified call (call lib/pgm) with no parameters passed, and
after it is called I need to determine which library it was called from so that 
I
can get that library into the library list (and I don't know what my libraries
name is at this point).

I ended up using an RPG program because the Program Status Data Structure can
easily provide the library name.  It was then just a simple matter of having the
RPG program call the CL program passing the library as a parameter.  Here's a
code sample;

D DeclareFields   DS
D  QualifiedName                21
D*
D PgmStatusDS    SDS
D  PgmLibrary            81     90
C*
C* Assemble the qualified Program name for the 'call' op code
C*
C                   EVAL      QualifiedName = %TRIMR(PgmLibrary) +
C
%TRIML('/PROGRAMA')
C*
C* Call the CL program passing the Library name.
C                   CALL      QualifiedName
C                   PARM                    PgmLibrary
C*
C                   EVAL      *INLR = *ON
C                   RETURN

It's not a CL solution, but it does get the job done....

It was after I got this working that I read Brendan's solution, and I have to
agree with Dave that it is really quite brilliant.

Thanks again to all,
