>Can anyone tell me where I could find  a LL(1)  grammar of modula-2??

The syntax of Modula-2 is not easy to convert to LL(1).  For
example, the designator/qualident problem:

  designator ::= qualident { '.' identifier  |
			     '[' ExpList ']' |
			     '^' }.

  qualident  ::= identifier { '.' identifier }.

See the problem ?  You will have to do some semantical analysis.
Within these restrictions, I have a LL(1) grammar for Modula-2
available.  Just mail me.
