Re: Service programs and QSRVSRC

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

Point well-taken. However, I'm working in a vendor situation - as much 
as possible, we want to avoid making the customer have to recompile 
anything that uses a *SRVPGM we distribute. Therefore, I don't use a 
version number. If I needed to force recompilation, I'd use some rename 
of the signature - perhaps a version number that's not there now.

Nonetheless, IBM do not typically use version numbers. Not that they are 
the be-all-and-end-all!!
