Re: Really basic question - File Description

[Jerry Adams <jerry@xxxxxxxxxxxxxxx>]

I doubt that there is a one-size-fits-all answer to the question.  If 
the program uses Except operations (which is quite conceivable for a pgm 
converted from RPG II), the Write, etc., method won't yield anything.


Eric's answer (use DSPPGMREF) seems the most rational.  It sure saves 
scanning source.  Even if the file name in the pgm (such as FILEA) has a 
compile override to a different file (say, A.FILEA), a query over the 
outfile can still search for A.FILEA.  That doesn't, of course, always 
work or hold true for program-described files.
