Title: RE: Changeing records in a big file

Have you tried SQL or OPNQRYF?  They seem to block records in chunks of 20000 or so, and they fly compared to RPG.

Subject: Changeing records in a big file

I have a 4 million record file that I need to change some records in if they meet certain criteria.   What are some things I can do to speed this up. obviously sequential reading of the file is out of the question at over 4 hours to run.  I would prefer not to use the SETLL if possible,  because I don't want to have to go in to the file and see what record to start with.

thanks for any help.
