Before I waste any more time on this, I'd like to know if anyone else has
encountered this problem...

Fish disk #5 contains code for accessing the input device (out of the RKM).
When I compile input.dev.c, I get an error message on line 170 because
a VOID data type is used in an assignment (Lattice error 91, a no-no).
This is the line:

	handlerStuff.is_Code = (VOID)HandlerInterface;
		/* address of entry point to handler */


Previous to this, there is the declaration:

	extern HandlerInterface();

The external function is a small assembly language module that allows the 
input.task to communicate with a C language routine.

Anyway, I took out the cast '(VOID)', compiled, assembled, linked, and the
program crashes the machine right after giving the message that it has
opened the input device.  It also requires a lot of stack space for some
reason.

Not having any experience with the input device, nor with linking C and
assembler routines, I ask you;  Have you succeeded where I have failed???


Thanks for any advice!
