<<<< < i< What the advantage of using self-modifying code that non-self-modifying code cannot achieve? --------- Job Security... I once traced a problem in some PC software to a bit of SMC that worked on a 8088 but not on a 8086. Turned out that the larger prefetch of an 8086 would grab the old data before the write and use that instead of what the programmer intended. John Eaton !hpvcfs1!johne
