Re: Binder Language problems

RTVBNDSRC is a tool to assist you in creating binder source for use by
the CRTSRVPGM command.  The binder language tells the CRTSRVPGM "binder"
the order in which exported symbols are to be seen by the service
program's callers.

You should be able to use the output of the command directly, with the
following changes.  RTVBNDSRC always seems to create a PGMLVL(*CURRENT)
parameter on the STRPGMEXP command.  Just be sure that, except for the
most recent set of binder language, PGMLVL is set to *PRV.  As long as
you leave the LVLCHK parameter at its default of *YES, you should be
able to have multiple sets of exports, with different signatures,
peacefully coexisting within your service program.  Calling programs
compiled with older signatures should still find the correct set of
exports.

You say that "To get clean compiles ...".  What happens if you just
change all of the STRPGMEXP commands, except the current one, to specify
PGMLVL(*PRV).  Why doesn't this result in a clean compile?
