RE: Weird output of bison (or flex)

[Xinan Tang]

Hi 
 
   This might be caused by regular expressions were not recognized by FLEX. The 
defualt action is to print out whatever found to the stdout.

        While the parsing is being done I get weird outputs such as
        <>.<>.<>.<>.<>....<>.<>.
        
        as much as I could understand, they might be related to 
reductions/shifts,
        but I'm really not sure about it - just a hunch "(since the output is
        different with every input).
        I couldn't find the code which generets these outputs.
        how can I avoid them?
        what do they mean?
        
        The outputs are printed in stdout.
        I'm using bison 1.35 and 1.28 on LINUX and AIX and it always happens.
        Just one last thing - I'm also using flex, and it might as well be 
generated
        from that....
