I disagree with your assessment of the "way it is" for sites. It's an unnecessary change which was forced on us because of an error due to a request from a single user. It's not like the HMC is in and of itself an SMTP server. THe HMC doesn't have the capability to be an SMTP server. It's

Paul, The ssvt consists of a header, 256 byte table, and function routines. The 256 byte table can have two meaning sets of values; zero and greater than zero. If the function code is zero, then the sub system is not interested in the function. If the function code is greater than zero

By experimentation, V5.2 cannot perform INITCHECK at any OPT level even with REGION=1536M (the largest region I am allowed to use here) for very large programs (30K+ lines actual code). It does succeed at OPT(1) and OPT(2) for more reasonably-sized programs (less than 6K lines) with

Hi Todd, I know that SHA-256 is available in CPACF (and I've written Assembler code to use it).My assumption is that using Vector integer instructions to solve many hashes in parallel would be more efficient. CPACF SHA-256 (for one hash) is much better than equivalent GP Integer

Although I can't see it documented, I suspect that INITCHECK can only be offered as a side-effect of the complex analysis which is already done for the higher levels of optimisation, and which is not done at the lowest level of optimisation (OPT(0)). The message is probably correct, but the
