Re: Prototyped Procedures

Hi Mike

<snip>
A number of you have mentioned service programs

I have started to create prototyped procedures but not service programs

What are the differences (Coding, Calling, Compiling)
</snip>

Service programs are basically one or more procedures compiled into
modules and bound by the CRTSRVPGM command.  This is useful if the
procedures are used in many programs.  If you want to change the
processing of the procedure, you only need to re-create the module,
and do an UPDSRVPGM, and all calling programs will be updated
automatically (if the prototype doesn't change).  There is a wealth of
info on these in the IBM manuals, and also in the Sorcerer's Guide
redbook.
