Re: Address Space TCB Structure

If you have SDSF on z/OS 2.3, you can issue the "JT" action command against any address space to see its TCB/RB structure. The display indents the fixed field TCB one character when it is a daughter of another TCB. Rob Scott Rocket Software -Original Message- From: IBM

Re: *+n branches

Personally I think all *+n branches are ugly and dangerous. Inside a macro, I would use a generated label with some prefix and SYSNDX. Inside normal assembler, I would generate a real label. However, that being said, I use the HLASM structured assembler macros that solve all these problems for

Why not use MVCDK to update the non-key8 storage? That is fine for fields where you are replacing the entire contents - but how about an individual bit in a status byte for example where normally you would use OI/NI or OIL/NIL ? Rob Scott Lead Developer Rocket Software 77 Fourth Avenue

My advice : (1) Use an STIMERM exit (2) Use multiple ECBs in the mother task - one for the STIMERM exit to post and another for ad-hoc interrupts/requests (3) WAIT on an ECBLIST instead of just a single ECB (4) You can then examine which ECB pops and take actions accordingly Rob Scott Lead
