I would have thought this is an incredibly *minor* reason to move to ILE.
After all, as David has discovered, putting an indicator on the RPGIII OPEN
statement avoids an error anway. Adding your own flag to check this is also
easy.

Frankly, knowing whether a file is already open is something I rarely (if
ever) make use of, unless I know that the procedure in which the OPEN is
coded will be called thousands of times, where, I guess, a 'failed' OPEN
plus the exception check it causes (which is caught be the indicator or
whatever) might make a hit on performance.

All that said, I would run CVTRPGSRC on it.
