Re: [Grammatica-users] Tokenizer problem

[Anant Mistry]

Ralf,

A possible solution would be to define 

COMMAND = "GO "

That is a string of "GO" followed by the space character.
It makes your production

INPUT = COMMAND LETTER+;

Hope this helps

It seems that whenever letters are defined as tokens, they may not occur in other context. But I am sure there is a way around this problem, can someone help me?
