You could, but then again there is nothing prohibiting a S/36 program from
processing an externally described file.  It's just program described because of
compiler limitations.  BTW it's no different than program describing an 
"external"
file in RPGIV.

The program has to make sure as to not introduce data decimal errors.

During our transition we noticed such nice things like a program described 
indexed
file with EXT for key start postion would use an external  logical with more 
than 3
key fields bypassing the BLDINDEX limitations.

We sort of thought of S/36 RPG compiler as the same as the RPGIV compiler with
certain opcodes flagged as unavailable.  Maybe the same way that release
compatability is managed.
