Translate $ISA as "Instruction Set Architecture" or perhaps processor feature and favor hook. On most intel/amd... boxes ISA issues are transparent so this is not set. Some folks do get hit by 386/ 486/ 586/ 686 differences when they fiddle with hardware in the wrong compatibility direction. By setting $ISA an optimized, feature extended or compatible library could be found first. Try to not confuse it with the other 500 uses for ISA (like Industry Standard Architecture.
