[antlr-interest] Ident with ending In or Out word

[Roohul]

Sorry for that..

when i use only letters (a..z | A..Z) in the variables and connectors it give an error while creating an AST that "no viable alternative at input 'real'" and when creating variables with digits the grammar do not compile at all and give the following error. 
"The following token definitions can never be matched because prior tokens match the same  input: Alpha"

I hope that it is more elaboration.. 

Regards

Hi,
This is my sample grammar.. this did not work.. another thing is 
that my variables and connectors both can have digits so I created Alpha
 : LETTER (LETTER | DIGIT)*; for this but it also give an error. 


The problem descriptions "did not work" and "also give an error" do not tell much. Care to elaborate?
