Mitch, When I say source code, I mean assembly language source too! In Windows a "selector" functions just like a segment. You can move the selector's value into the DS and ES registers and then manipulate data within that portion of memory. Selectors are similar to "handles" in that they don't correspond to a physical memory location. Rather, in protected mode, they tell the processor that it should consult its internal table of physical memory addresses and use the one associated with the selector. Mark
