hi !
I am facing one problem with a grammar of this type :
Assignment:
TypeAssignment ValueAssignment SupportingProductions
;
TypeAssignment:
TYPE NAME '=' Alist
;
ValueAssignment:
VALUE '=' Alist
;
SupportingProductions:
NAME '=' ProductionList
;
Alist:
Item
| Item Alist
;
ProductionList:
Item
| Item ProductionList
;
Item:
NAME
| INTEGER
| REAL
;
Ok...the elements in caps are the tokens...now if i give a input like
TYPE Ele1 = INTEGER Another
VALUE = 1
Another = REAL
It gives me an syntax error..ideally i am trying 2 replace Another with
REAL.
But it gives me a syntax error !! It does not come out of the
ValueAssignment ??
Anyone has any suggestions where i am going wrong ??
Thanx,
Rutu
