Kris:
Be nice, please - he was kind enough to send me the code to see a
"living" example! :)

To all readers thinking they'd nee to intercept the message of an
arriving spool file: it leaves a hole: reader files sitting there before
WAKEUP/PIPE/xxx were active remain in the reader until another RDR file
arrives. WAKEUP hasn't that problem.
And, you can save yourself a lot a work by looking at my RxServer
package: it handles reader fies etc, built around WAKEUP, with built-in
security etc.
2008/7/1 Hughes, Jim <[EMAIL PROTECTED]>:
How would the STARMSG pipeline detect someone typing a message
at the console and hitting the ENTER key? Would it require another
concurrent pipe running?
I like WAKEUP because I can set timer interrupts, reader
interrupts, message interrupts, and console interrupts.

Well ... everyone was saying "use WAKEUP" and that's good
advice, but I prefer to start with Pipelines. Pipes would catch all
those messages you're interested in.
Your EXEC would look something like ...
/* REXX */
'CP SET IMSG IUCV'
'PIPE STARMSG | REXX MYTHING'
And then MYTHING REXX might begin as ...
/* REXX */
Do Forever
'PEEKTO RECORD' /* examine the record, but do not consume it
*/
If rc ^= 0 Then Leave
/* parse the variable "record" and figger things out */
'READTO' /* now consume that record and loop to get another
*/
End
You can do all of this with WAKEUP. The calling semantics are
different.
