The "pascal programmer's guide" (I have Sun unix: is this part of the 
berkley distribution?) says you can declare C library calls as:

	procedure thingy( <appropriate declarations> );
	external c;

and calls to fortran as:

	procedure thingy( <appropriate declarations> );
	external fortran;

Any you have to look up how do declare various kinds of parameters.
For C, at least, strings get declared as conformant arrays of characters;
most things get passed as "var".  Then you also have to link in the
appropriate library (i.e. -lc)
