(Apparently, they're also used as scratch space by the ROMS.) However, ApplScratch (I don't have IM with me, so I think that this is the right symbol--I don't know the memory address) is 12 bytes of scratch space useable by the application, and guarenteed unfussed with across ROM calls. Most likely, I'll try patching my copy of the Megamax C compiler, and re-compile the syslib file and see if it works on our institute's Mac II. - William Woody Mac! > ][n && /|\ woody@tybalt.caltech.edu woody@juliet.caltech.edu
