[antlr-interest] Concept Problem with recognizing Tokens

[Jeff Skaanland]

Hopefully this isn't just something I've been overlooking in my searches
but....

I'm processing a type of assembly language and am running into a problem.
Outside of Labels, there is a set amount of vocabulary for the language
which I defined as tokens (MAC = "mac"; ALU = "alu"; ...).

Problem I face:
         When I intentionally put an error into the input stream, for
example use 'Mcdonalds' as command, instead of saying "found MCDONALDS,
expected MAC" it reports "found 'c', expected 'a'.  To fix this, I wished to
process every word into a token, but then I can't figure out how to take a
token, INSTRUCTION, and then check to see if it's actually a MAC token or
ALU token and, if not, spit out "Found MCDONALDS, expected RUTHS_CHRIS" (Or
expected MAC again...)	

Thanks for setting me straight,
