RE: /FREE RPG compiler errors

Joe,

That is only readable if you know that A is numeric, B is alpha and the 
sizes of each and all of the various other RPG rules dealing with MOVE.

Pure free-format is not necessarily "better" than fixed-format.  There are
some things better, some not.  And it *IS* an opinion.  Replacing:

   MOVE A    B

with

   eval %subst(b : 2 : 2) = %editc(a : 'X');

is NOT better, in my opinion.  I don't care how readable it is to a C
programmer, I care how readable it is to an RPG programmer, and the former
is more readable, and a lot easier to code.  This is where the opinion bit
comes in.

Now, most of my objections would go away if they'd just allow some
transitionary syntax.

   eval %move(a : b)
   eval %movel(a : b)

If those were acceptable, I'd be far more likely to embrace the language,
and there's no reason not to support them.  You think they're unreadable?
Go in and change them.  But don't force your idea of readable on me.

Joe
