I'm afraid that was my fault, Bruce.
I went back to my original reply and saw that in my haste I left off the last
word of my thought. It was supposed to read:
"...we were never even able to get IBM to port Classic Stream I/O
to the z/OS _interpreter_."
(This is indicated by the odd reference to "the z/OS"; it was supposed to be an
adjective.)
So I apologize for the misleading post; I was quite aware of the availability
of
Stream I/O on z/OS as a part of the Rexx Compiler. Unfortunately, that is not
sufficient for the adoption of this superior I/O facility by the legions of
REXX
interpreter users. If Stream I/O is available only on certain userids, outside
the standard support and maintenance structure, it simply will not be used
except for personal toys.
Although Stream I/O was long in coming to the REXX interpreter on z/VM
(relative
to its introduction in OS/2) it has been there for years, so its absence on
z/OS
(IBM's "flagship" OS) is all the more disgraceful.
I can probably put my hands on a copy of the Stream I/O package if you would
like a copy.
