Why did you switch?  Something Lattice C does that cannot be performed in
Modula-2, code efficiency or just for fun?  

C doesn't support nested subroutines, unlike M2 or Pascal.  You can get 
the effect of "local-global" variables, and probably the speed as well,
by building a structure that gets passed to every function in the logical
group and using registerized parameters in Lattice V5.02.  C++ give you 
this effect even more so, though if you're at all used to the speed of
Benchmark compiles, you'll probably choke on how long it'll take to go
through a Lattice C++ compilation (still, I like the language).  Also, 
there's no source level debugger for Lattice C++ yet, while I just got a
look at the new Source Level Debugger for Benchmark M2, and I like it
better overall than Manx's SDB or Lattice's CodePRobe.  TINAR, of course...
