I'm trying to adapt the Open COBOL grammar to ANTLR and I'm struggling a
little... My goal is to build an AST of a COBOL program. I'm not too
familiar with lexers/parsers...
How can I deal with the line number that starts each line?
It seems in the OpenCobol grammar, it is suppressed by a pre-processor
but I wouldn't mind having it in the AST.
How to build a Lexer rule for the line number?
Here is a COBOL line example
000010 IDENTIFICATION DIVISION.
And I want to deal with the starting 6 numbers...
Thanks,
