Hi Rob--

    This use of pipes with RXQUEUE is mentioned in passing (in
REXX.INF), but there is no example of how to use it.

    You will find the example in the hard-copy OS/2 2.0 Technical
Library volume "Procedures Language 2/ REXX Reference." (p/n 10G6268).
If you know what you are looking for (which hardly anybody does when it
is needed it for the first time) you can find the piped-queue construct
in Chapter 12, "Useful OS/2 Commands" in the code snippet illustrating
the use of "Queue Services (Filters)."  Unfortunately,
"pipes" is not
found in the manual index, so you have to read the entire manual to find
it.

    As far as I have been able to determine, this example is not in
either the REXX.INF file nor the REXXAPI.INF file (that comes with the
Warp Toolkit).  The latter is the only on-line reference I am aware of
that discusses the interfaces between OS/2 REXX and other programming
languages.  However, the pair of them are still incomplete, as compared
to the hard-copy manual mentioned above.

    Regards,
