Precisely. One seeking to use a tool program executable does not look in the C/C++ development manuals. One looks in the manuals that document the tool program.
I said "undocumented" exactly because the Unix System Services manuals do not say which tool programs use open() and which use fopen(). They only say what they will support to work with MVS datasets. And of course it will stay that way because they could change the source of any tool program at any time they feel like it and start using open() instead. I was just describing what exists (for now).

"awk" is one tool I have successfully used to do this. Undocumented? It is well documented in the C/C++ manual. Just not in the UNIX manuals. And the UNIX manuals do not tell you which utilities use fopen() and which use open(). Programs which use open() cannot support the "//dsn" or "//dd:ddn" method of opening MVS "legacy" datasets. _ This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
