When it comes to sheer I/O power for copying one sequential file to another, *nothing* beats the muscle of the xxxGENER sort products. All it can do is copy input to output. No reformatting or other tweaking. You wouldn't notice the performance with 100 records, but try 100K or 100M Astounding.

I have only vague memory that it's QSAM operator, where IEBGENER is BSAM, and evidently, one buffer. It's also a fairly trivial exercise to write your own "fast" copy program. QSAM is pretty fast with optimal bufferage. However, I assume that the SORT programs are going to win with large datasets. sas 2018-05-22 15:47 GMT-04:00 R.S. <[email protected]>: > Just curious: which company delivers FASTGENER? > > I know ICEGENER (IBM) and SYNCGENER (Syncsort), but don't know FASTGENER. > Are ther more "GENERS"? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
