[antlr-interest] Check individual stmt?

[Bill Steer]

Hello.  My grammar processes a "program," which consists of individual 
"statements."  Those statements are just semicolon-delimited 
expressions.  I'm storing all of the statements in a string and using 
the corresponding string as input to ANTLR.  So far, so good.  But I 
need to check the content of each individual statement to see if the IDs 
in it are in a symbol table or not.  Is it possible, from an input point 
of view, to send ANTLR a series of statements, one at a time?  I'm 
thinking here about the ANTLRStringStream, not the rule to run.  Do I 
have to create a new ANTLRStringStream and corresponding lexer each time 
I feed it a new statement, or can the ANTLRStringStream be reset to a 
new input string?

Thanks very much for any help.

Bill
