Hi Ned,

Yes, it works. However I do have to compile the program, find out where it
puts the functions, and then edit the program to set PCLATH accordingly.
It is a hack, but it does work, and probably what I will end up doing.
However I do not trust it. I suppose it's always good to look at the
assembled output and hand step it :)  Here's a test that does work:

#include <pic.h>

unsigned char a;
unsigned char b;
unsigned char c;

void first(void);
void second(void);
void third(void);
void fourth(void);
void jumptable(void);

void main(void) {
        c = 3;
        jumptable();
        while (1);
}


void first(void) {
        a += b;
}

void second(void) {
        a -= b;
}

void third(void) {
        a += a;
}

void fourth(void) {
        a = a>>1;
}

void jumptable(void) {
        asm("movlw 3");
        asm("movwf 0x0A");  //THE HACK - LOADING 3 INTO PCLATH
        asm("movf _c,W");
        asm("addwf 2");     //ADDING TO PROGRAM COUNTER
        asm("goto _first");
        asm("goto _second");
        asm("goto _third");
        asm("goto _fourth");
}
