Hi,
I have a multitasking CMS application that waits for a number of
different types of events and I would like to add a new event type that
represents data from the CMS stack. I thought that the obvious way to do

that case, the CP stage issues only the commands that it reads from

I haven't experienced this specific problem because IBM strongly advised
us to not allocate more than 1 virtual CPU to a mutitasking CMS
application. The reason they gave was that any CMS services called from
a thread running on a non-base CPU would need to be scheduled to run on
the base CPU, so
This doesn't completely answer your question, but I was told that because the
people writing Multitasking CMS were limited in how much of CMS they were
allowed to change, that most traditional system calls are scheduled to the base
CPU. Therefore, providing multiple CPUs can actually degrade
If you need to edit data with non-printables, ensure that you have IMAGE

x'05' as TAB characters and x'16' as backspace characters.

The problem is that I may eventually need to do a ThreadCreate (note
Multitasking CMS call, not POSIX pthread_create) or EventTrap call, but
not initially. It seemed pretty ugly to me to have to create a thread

I think the mechanism for redirecting VSAM requests to DB2 VM was the
SUBSYS operand on the FILEDEF command that allowed a VSAM emulator to be
provided. I was hoping that this might provide a mechanism for us to do
something for NetMaster in VM, but unfortunately the facility was never
provided
