[antlr-interest] Error in predicate logic

[Gerald B. Rosenberg]

Thanks much for the help, Gavin.

You were right about the unanticipated consuming of the 
non-SEMIs.  Missed it in my test case.  Seems the  ~(GRIDLET | 
LETTERS) is not needed because of how Antlr resolves equal length 
matches.  This should be the final version:

SPCHAR : { !tagMode && !attrMode }?=>
     ( AMP GRIDLET INT SEMI                     { printState("SpDigit "); }
     | AMP LETTERS SEMI                         { printState("SpLettr "); }
     | (AMP GRIDLET INT ~';')=> AMP GRIDLET INT { $type=PCDATA; 
printState("P2Data  "); }
     | (AMP GRIDLET ~INT)=> AMP GRIDLET         { $type=PCDATA; 
printState("P3Data  "); }
     | (AMP LETTERS ~';')=> AMP LETTERS         { $type=PCDATA; 
printState("P1Data  "); }
     | AMP                                      { $type=PCDATA; 
printState("PcData  "); }
     ) ;
