REXX isn't the problem. Your coding technique is.
There's no limit to the size of file you can read and process using REXX,
--provided-- that you read and process only one record (or at most only a few
records) at a time, like 'normal' program would.
For example:
EXECIO 1 DISKR MYFILE
IF RC <> 0 THEN DO
....whatever your end of input file logic needs to be....
END
PARSE PULL BUFFER
(...BUFFER now contains the record you just read from MYFILE...)
...etc...

Subject: EAGREX0500E Error 5 . Machine storage exhausted or request exceeds
limit in REXX
Hi all
We want to handle a big file (about 5,000,000 records in it) by REXX. We
also compile the Rexx PGM by REXXCOMP
----------------------------------------------------
//COMPILE EXEC PGM=REXXCOMP,PARM='ALT SL COND TRACE'
//SYSIN DD DSN=yourlib.SYSEXEC(REXXIN),DISP=SHR
//SYSCEXEC DD DSN=yourlib.SYSEXEC(REXXOUT),DISP=SHR
-------------------------------------------------------------------
After we submitted the JCL using the REXXOUT with REGION=0M, We got the
following message:
EAGREX0500E Error 5 . Machine storage exhausted or request exceeds the limit.
Our questions:
1 Could REXX handle more than 5,000,000 records files?
2 Is there any way to solve this issue?'
Any suggestions would be greatly appreciated!
Thanks a lot!
Best Regards,
Jason Cai
