I don't know how the internals of the z machines work (behind the ISA), but if they are like Intel, where the ISA instructions are "decomposed" into micro-ops, that might be a real nice way to tell the machine: "these instructions are a loop - create a micro-ops program and run it." > Charles > > -- Advertising is a valuable economic factor because it is the cheapest way of selling goods, particularly if the goods are worthless. -- Sinclair Lewis Maranatha! <>< John McKown
