I've started a group called RQCOMPILER over at http://groups.yahoo.com/group/rqcompiler . We plan on making a compiler in C++. However, we need some help from C++ coders.
If you want to help make a compiler that reads a BASIC language and produces ASM output (Vasm) and then an exectuable, see the link above.
The language will be similar to RAPIDQ-BASIC and is called "KoolBasic" presently.
