There's always some gotcha. I did a conversion of a bunch of programs some years back from S36 to RPGIII (on an as400), and that was even keeping the files internally described. Things like a field name can be in a record format and a bunch of different DS's at the same time. If it's in two DS's at least it'll stop the compile. You can get subfields of another field that overlap other subfields fields, and sometimes a field overlapped part of two fields! (Whoever would've thought?)

Another thing once was where for some reason there were strings of nulls in some wierd place embedded in an externally described file, had to have been put there by some RPG program(s) using the file as program-described or something.

In other words, if a bunch of programs are accessing that same file, you might get a rude surprise if/when you try to convert to externally described files.

If the company is still pure RPG-II and pgm-described files, if this is a first time around, I'd probably "play it safe" and keep the file as program-described. Meaning if the programmers weren't kept to some tight consistent standard, there might be some surprises.
