[antlr-interest] new fish with binary file scanning problem

   I'm trying to scan/parse the binary file, which has part header 
decription like this.

   Field        Type
   [N]bits      UB(5)
    A           SB(N)
    B           SB(N)

   since A and B have to be determined by the first 5 bits, I'm sort of 
stuck on how to define my lexer to have dynamic processing. is there any 
good solution or idea on dynamically parsing, something like Syntactic 


Thanks a lot~~
