Roops,

?

When I co-wrote Top Secret Security for MVS in 1981, I wrote an APF-authorized tester nicknamed ACETEST, similar in concept?to TSO Test but much smarter -

?

It can run as an STC, Batch job, TSO command, or best as an ISPF Application.

?

As an ISPF application, it supports full screen viewing of the PSW, registers, and memory,?and?you can edit memory simply by over-typing.

?

You can test both APF-authorized and non-authorized programs.

?

Full breakpoint support is available, and the greatest feature is that you can set a breakpoint, then go into STEP mode, which allows?you to step through code one instruction?at a time. After each instruction is executed the PSW, registers, and relevant storage areas are displayed. To step to the next instruction all you have to do is simply hit enter and the step breakpoint will move automatically to the next instruction to be executed.

?

You can?set breakpoints in code which has been loaded into CSA or SQA. You can even set a global breakpoint in?common code (except real LPA), such that when any program in any address-space hits the breakpoint, Acetest is?automatically invoked, like an intelligent SLIP trap.

?

You can test multiple programs at the same time as each program runs under its own TCB. I used to bring up IMS and CICS under?Acetest all the time. Then I could put breakpoints in Top Secret code, or in CICS code for example. I remember testing CICS MRO, and having 4 CICS regions, each running in its own address space under?Acetest, with breakpoints all over the place...

?

Acetest also has features like?FIND, which will find a data string anywhere in memory, WHERE, which will?tell you where a given address is, as in what offset in what module, or what?subpool.?All of the syntax is simple command based, like LOAD modname1, AT R3%+20, ASCB+40%, etc.

?

I automatically include ACETEST with my ISPF. If you wish I can send both to you.
