Sorry. I mis-read Wayne's assertion. He was stating that GETMAIN and
STORAGE behaved differently. They don't.
The rest of what I wrote below is accurate ...
Just because the operating system doesn't guarantee the storage is
zeros, doesn't mean it won't be zeros.
That's precisely why serious z/OS software developers use DIAG TRAPs
like IgvInitCpool and IgvInitGetmain to force all acquired areas that
-- according to the rules might not be zeros -- to not be zeros. (We
also use IgvInitFreemain to help catch late references.)
