RE: gnubol: Hacks needed to parse COBOL

["William M. Klein" <wmklein@ix.netcom.com>]

I don't know if there is any thought of taking your GNU compiler thru the
CCVS (certification) tests.  If so, it IS important to point to the right
columns - at least for items that are flagged in those tests.  When NIST ran
the tests, they manually checked that you got each line and column correct
(but this really only applies to items that are outside a specified subset of
the Standard - not for extensions or syntax errors).

Having said that, I do agree with Randall's comment on this particular
syntax.  As far as the '85 Standard goes, something is wrong in the
subscript - but you can't really tell what.  If the C is actually an element
in a two-dimensional array, then it is the parenthesis that are wrong, not
the number of subscripts.
