[GNU-COBOL] cocom

[Michael McKernan <mck@tivoli.mv.com>]

The Russian Armoury, eh?  I actually pulled this thing off the net
about five months ago, but never got around to looking at it.  The
following produces eight (what appear to be) harmless shift/reduce
conflicts.  Oddly, having on_size derive "[ON] SIZE..." comes up with
reduce/reduce conflicts.  ???

add:    ADD
        ( CORR identifier TO identifier [ ROUNDED ]
	| (identifier | NUMERIC)+ 
	  ( GIVING (identifier [ROUNDED])+
	  | TO ( (identifier | NUMERIC) GIVING (identifier [ROUNDED])+
	       | (identifier [ROUNDED])+
	       )
	  )
	)
        [size_error]
        [END_ADD]
;

on_size: ( ON SIZE | SIZE )  [ERROR] statement+
;

not_on_size: NOT on_size 
;

size_error: not_on_size [on_size]
          | on_size [not_on_size]
;

identifier: IDENT ( ( OF | IN ) IDENT)*
;
