[pet] Flop fails to compile grammars created with the lingo matrix

[Coote, Ravi]

Dear list,

Has any body ever tried to flop grammars that were created by the lingo grammar generation page:
http://www.delph-in.net/matrix/customize/matrix.cgi ? I am having problems to compile the minimal english example of the Lingo Grammar Customization page. Flop fails with many syntax errors (see below). The error log of flop is attached.

Can somebody tell me, of what format the input grammar for flop has to be? Is there a minimal example from which i can derive my grammar, that's compatible with flop/pet ?

Thank you for any hints.

Kind Regards,

Ravi Coote
