"Please stay in touch and let us know how you are proceeding." I completed the program. I can now drive a flash copy of our IMS system using the messages extracted from the production IMS log, and requeued via MQ/OTMA, also checking the output messages produce matche what is expected.
This means I can regression test, or performance test our mainframe 'SOA' workload, which has been next to impossible to do up to now. I also don't need the off mainframe systems to do it. This will be very useful for testing new releases of z/os, IMS, DB2 and MQ before we hit development. It's not often I get a chance to do any programming, but I found this very enjoyable. The 64 bit instructions are very handy, but I must confess I really liked the 'LAY' - so useful to be able to use neg offsets. Thanks to everyone for their help and suggestions. Joe
