Thanks Dave. #2 appears to be the answer. I started relearning the Mits codes from my Pronto, and they seem to work perfectly. Actually, it is a VERY rapid process, since the screens are identical to the Pronto screens. So I have my iPaq face the Pronto, each with the same screen displayed, and go through each icon to learn the base commands. Sweet. If my aliasings still work, which I expect, then my macros should start working soon too.
