Re: retrieve service program list of procedures

I would not use the QUSRTVUS program - I'd use pointers. First, have a DS for the generic header - based on a pointer, which will be the address of the user space - there is an API to get that address (Retrieve Pointer to User Space (QUSPTRUS)). Have a DS defined to match the MODL0100 format - there should be one in QSYSINC/QRPGLESRC that you can model after - and base it on a pointer. Set the entry pointer to the address of the user space you retrieved, plus the offset to the list as found in the generic header.

Thanks for the clarification on that point Vern. It's been a while since I've used the user space APIs, and I forgot that QUSPTRUS was the way to get a pointer to the user space, rather than QUSRTVUS. I'll have to look in to QUSRTVUS so that I have an idea about this alternate method of accessing user spaces.
