And I knew you would suggest USRSPC ;-) BTW the program is ILE/C and I
currently use shared memory.

I guess what I'm really after is a way of having a kind of singleton *SRVPGM
(not just the data segment in a shared AG, but the code segment too) across
processes that is provide by the system. I can do it by having a 'service'
type job, but rather than have to code one, it would be nice for the system
to provide it - can anyone say SOM Object ? ;-)

I understand that the underlying task switching almost provides this, as I
think that only one copy of the code segment is paged in to active storage
regardless of the number of processes that use the code, it's the seperate
data segments that keeps things at the 'individual' level.

I guess when you get to the point when you're eaking the last bits of speed
from something, you start thinking "..if all these processes all shared the
same data, or even better, all shared the same data and code - just one
active set of both on the system...hmmm"

But I'll take your advice, I'll not wish too hard for it...
