If possible, look in "Teach Yourself ReXX In 21 Days' by William
and Esther Schindler, pages 401-403.
You direct LineIn() and LineOut() to file 'QUEUE:',
and replace any test for end of queue with Queued().
Example:
/* ReXX */
'find "REM" \config.sys | rxqueue '
/* This uses the default queue, SESSION */
DO WHILE ( Queued() >< 0 )
inline1 = LineIn( 'QUEUE:' )
SAY 'Test.....'
SAY inline1
END
I just cranked this out a few minutes ago as an example.
Rxqueue.exe, etc. really serves the same purpose for ReXX
in OS/2 as input from a pipe for PERL.
Queue() (function, not filter), can be used to set up
multiple queue's if needed.
'QUEUE:' is an under-documented feature. ;-)
