Depends.  For a 20,000 line program, 1 or 2.  If I was only adding a few
of lines, I'd pass on /free.  If I was changing a significant part of
the code, I'd rewrite the section I was working on.  Or, I might make a
new /free module/program for that file and call the program from the
first program.

Each shop has to decide how to procede.  But the issue is similar to
dealing with converted RPG III code that has

C          A        IFEQ      'X'
C          A        OREQ      'Y'

When you're changing the code following that IFEQ/OREQ, what do you do? 
What if you're adding a case for 'Z'?
