I noticed that the comp.compilers FAQ had a question about COBOL
grammars. I decided to write one. Now what I have is full flex/bison
code to recognise ANSI-74 COBOL as per a self teaching guide.
The only thing it does not recognise is columns.
ie. an asterisk in column 7 meaning comment.
It recognises a program even if it is not in the correct columns.


Q: How do I do column sensitive scanning in flex ?
Q: Or should I write my own scanner ?


I'm thinking of writting a COBOL-74 compiler for Linux or cob2c.
Is there a good ISAM package for my run time lib ?
