-: Write an interpreter for a C-Like Language.

Is this the way gnuplot (for example) `reads' functions for plotting?
I suppose I could toss everything into a Tcl environment, but that
would be massive overkill for this application.

-: sounds like a lex and yacc job to me. (or flex and bison,
-: if you are gnu to this... ugh)

Yes, that's the direction I initially took, but it gave me nightmares.

-: Use DXEs:
-: 1. Call to gcc.exe to compile the external C file.
-: 2. Call dxegen.exe to make it into a DXE.
-: 3. Load it with _dxe_load().
-: 4. Run it.

Ok, I like this idea.  It sounds straightforward and involves minimal
overhead.  I'll take a stab at it.

Thanks to everyone who replied.
