	If you're using THINK C 3.0 and later, and THINK Pascal 2.0 or later,
you can compile your C routines into a library, and add the library to the
THINK Pascal project. The C routines must follow these conventions:

	- They must be declared as "pascal", as in "pascal void foo(a,b)"
or "pascal long bar(z)". 

	- They can't use string constants or floating-point literals.

If you want access to Pascal global variables, just declare them as "extern"
in your C code, and in your Pascal interfaces, put them in the interface-part.

 assembly-language listings and I spend more than 50% of my time in TMON.
