According to the November 1998, Volume 1, Number 1, issue of AS/400 Experts Journal; in an article by Skip Marchesani: Access Paths are a Good Thing There is a myth in the AS/400 community that is no longer true. That is: Access paths (logical files) on a file are resource intensive, have a negative impact on performance, and should only be used where absolutely necessary. This is no longer true in today's environment on the AS/400! The myth stems from the S/38 and was the guideline that IBM was giving customers at that time. The Rochester development lab began to change the algorithms for access path maintenance in Version 2 of OS/400 and finished the task in V3R1. Access paths (logical files) are no longer the resource/performance hog they used to be on the S/38.

So far I have 26 different file formats. I was thinking of creating a physical file for each format and then a multiformat logical file. Will this multiformat logical file be a resource hog when used in various RPG and COBOL programs? Query? Is there a better solution?? TIA, Barb Nash PHB, Inc.
