[Cobolforgcc-devel] Re: GCC frontends

[Tim J. <te...@me...>]

James,

Yes I am still working on it. I am half way through doing 'IF' at
the moment.

Threee places to start:

1. http://gcc.gnu.org has a 'readings' link. The GCC manual is
also there.
2. The new 'treelang' language which is at
http://cobolforgcc.sourceforge.net/butree.tgz. IMHO this is a
much better 'toy' language. It is plaanned to include it into the
GCC source tree soon.
3. The COBOL complier manual has a guide on writing front ends at
http://cobolforgcc.sourceforge.net/cobol_14.html. 

Good luck!
