Re: Maintaining Service Program signatures

I would also assume that binder file as well as the prototype copybook
must be promoted to a production box along with the service program, but
the module would not since its incorporated into the service program,
unless of course the objects are recompiled when promoting which isn't the
case with all systems.

Hi,

IBM signatures do not include any information about the parameters of
exported procedures. This is a common misconception.

ILE Signatures are computed over the names of the exported procedures,
the number of exported procedures, and their order (sequence). Period.

Please re-read the excerpt (below) from a previous post carefully:

==========

... just memorize the rule: ALWAYS add new exported procedures to the
very bottom of the list in the binder source, and REMEMBER to add them
to the exported prototypes, and ALWAYS add any new parameters you're
adding to a procedure to the BOTTOM of the list of parameters and in
the code check the number of parameters before using the new one, That
way you can keep your signature the same and programs that use
"pre-existing" procedures will not break.

==========

This is very important to understand, or you will likely get burned.

All the best,

Mark S. Waterbury
