Re: gnubol: Record delimiter clause and parse order

Matthew,

In the standard the meaning of implementer defined name (assign
to printer) and literal-1 (assign to "xxx") are up to the
implementer. The interpretation below is MF's definition. Other
compilers do it differently. You can get the cobol 2002 standard
off the links off my web page and it has a list of changes from
cobol 85. MF's docs should say what is non-standard and what is
vendor defined. If you have the MF docs that is acually a big win
:-).

From memory, IBM Cobol uses the imlementer defined name as a dd
name in the JCL (similar to an environment variable, points to
the file). I would want to be able to be compatible with that.
Just try and keep it flexible and not hardwire any one compiler's
interpretation - especially any nonstandard keywords need to be
dialect dependent in the keyword table.
