... CONSTANT 1 2 CONSTANT 2 why reinvent the wheel? Why generate special case that may confuse an optimiser? Since constants already exist in standard Forth then wouldn't an optimiser handle them anyway (most seem to treat them the same as literals). The original question was producing an xt for specific literals, which IMO is exactly what CONSTANT does. George Hubert
.... How does defining 0 and -1 this way save op codes? Rick It doesn't really. as LIT val EXIT is three cells for any literal to compact into 1 word to call by xt. Does make me wonder about how an auto LIT compactor may work though. An auto LIT compactor...??? I think my brother has one of those in his kitchen. He uses it to smash the garbage into a small cube to go ...
... and there is no reason that 0 can't be one of these. My understanding is this exercise is a way to minimize the instruction set. How does defining 0 and -1 this way save op codes? Rick It doesn't really. as LIT val EXIT is three cells for any literal to compact into 1 word to call by xt. Does make me wonder about how an auto LIT compactor may work though. cheers jacko
