[antlr-interest] Simple parsing question

[George J. Shannon]

I have a parser that gets a MismatchedTokenException error that I would
appreciate assistance on.

Within the text being parsed is a simple rule that looks for '[' IntValue
']' where IntValue is the rule ('0'..'9')+ (i.e., integer value inside
brackets).

This may not be relevant, but I guess I should mention that this rule is
called by other rules, so this sequence is embedded inside other text.

Anyway, I get the MismatchedTokenException whenever I run into a '[0]', but
not when I run into '[00]' or any single digit other than '0'.

So, what's so special about 0 that I'm obviously missing?

Sorry to bother you with an obvious question; I have brain cramp after
staring at this for about an hour.

I'm using antlr 3.2 with ANTLRworks 1.2, but the error occurs with the
3.1/1.1.7 combination as well.

Thanks in advance for the help.

Regards,

George
