[open-cobol-list] Program-Names (was] two more things

[Bill Klein]

Roger,
  There was an interpretation request against the '85 related to
program-name resolution.

The answer was that CALL was supposed to be case IN-sensitive (whether using
call "literal" or call identifier).  The Standard doesn't allow literals in
the program-id paragraph (except in the '02 Standard AS EXTERNAL phrase).

COPY statements are the same (i.e. case insensitive).  

By this, I mean that 

 Call "aBc" 

is supposed to FIND

  Program-Id.  Abc.

It is reasonable (and as MF does) to have directives to control this - and
the NEW (in '02 Standard) AS EXTERNAL is supposed to help, but you should
(at least) have an option to ignore case in CALL resolution.
