I am also interested in the responses to the original question.
I provide a major subsystem with a very complex API on z/VSE. (EZASMI/EZASOKET)
One of our biggest issues is editing the addresses passed in the parm list.
While we have some code that seems to do the required edits, it's not what I
would call the best option. I am watching this thread because something might
be suggested that I can also do on z/VSE.
I don't know what is behind the OPs question, but it is a good question when
you are a subsystem or called API and you have no control over the caller's
code and what they pass.
.
The hardware provides the control. If, like some complex instructions
which perform a test execution, you are concerned with preventing side
effects of a failure you can verify input parms are readable with
CLC parm,parm
and that output parms are writable with
OC parm,parm
There is some performance penalty and dump reading challenge.
