Is there an easy way to know what programs on my system are using a particular service program?
How about an individual procedure within that service program?
</Greg>
I'm making my compiles allways as CRTxxxMOD followed by CRTPGM or CRTSRVPGM. After this DSPMOD detail(*IMPORT) and DSPMOD detail(*EXPORT) to outfile gives me a repository for all cross references.

I have a situation where I need to change the procedure interface of a function. I think I found all of them, but I can't be sure.
</Greg>

There is no need to change a procedure interface - never ever. The clean way is, to add a new pocedure with the modified interface, after this making changes where ever the modification is needed, if nobody is using the (deprecated) procedure it could be removed if somebody wants to remove. As a note aside: the new peocedure and the deprecated procedure could share most of the implementation logic.

BTW: same is true for most changes to PFs: use views only to access tables and don't change a view - never ever!!!
