I should think an indirect function call would be TRIVIAL on an 18C and
rather difficult on other PIC processors:

given:

void f(void)
{
}

void (*g)(void);    // g is a pointer to a func

// Assign pointer to variable
g = f;

movlw    low(f)
movwf    _g
lovlw      high(f)
movwf    _g+1

// Call thru pointer:
(*g)()

    push
    movf     _g,w
    movwf  tosl
    movf     _g+1,w
    movwf  tosh
    return
