RE: Sequence error in MR

...and it's just a matter of time before IBM introduces "RPG Logic Cycle
Feature" and "Cycle Tax".  If you're running programs using
primary/secondary files, matching records, etc. you'll have to pay for tiers
of Cycle Feature to enable your systems' CPW for those jobs.  Otherwise, in
addition to less efficient performance, RPG cycle processes will be degraded
by CFINT tasks.

There's one word missing from this discussion.  Performance. 
Now I'm citing numbers here from 10 years ago at least, on ancient 
hardware, but I rewrote a program someone had written to update a large 
master file from a transaction file.  It was written using either CHAIN or 
SETLL/READ (I can't recall) and I changed it to use MR logic.  The run 
time dropped from approx 4 hours to 40 mins.  And before anyone asks, no I 
don't care to recreate a similar test today, but if anyone want to go 
ahead I'd be happy to hear the results.  :-)
