It is well -known that we should avoid naming things the same as the

Now the parsing process has been changed in recent versions of the
editor, because of the fully-free capabilities now. I believe I heard
Barbara speak about this at COMMON or at one of the CAAC meetingsI
attend. Something like the first word on a line has to be limited to a
special set - Barbara maybe will chime in on this.

I'd love to hear that talk, but the general problem is that columnar RPG
'knows' a variable from an opcode because of the column the identifier
is in. Fully free RPG has to suss it out. So this abomination is
perfectly legal and compilable:

C IFLE IFEQ IFGT
C ADD 1 ELSE
C ELSE
C ADD 1 MULT
C END

but that gets weird in free:

if ifeq = then;
else += 1;
else;
end += 1;
endif;

The parser (in RDi and the compiler) gets confused. It gets better with
eval:

if ifeq = then;
eval else += 1;
else;
eval end += 1;
endif;

The parser is pretty good at what it does, but it can get lost if I do
something like put unmatched parens and quotes in weird places.
