Some nuts & bolts questions. Does anyone know how to: (1) Change the name of a diskette volume (the name you give when FORMATting, which gets wiped out when you BACKUP to it). This name is stored on Track 0 and probably takes some very low-level CCDISK calls to get to. (2) Exit the editor without updating (writing) the original file, as when you screw up. The Q command does an update automatically. Blieve it or not, none of the abort characters (break, ^C,^D, ^E, clear-break) will kill the Editor; it just keeps on coming back. So far, only the RESET button behind the Coco will save your file. Is the only hope to copy the file before editing? Oversights like this do not enhance OS-9's reputation for user-friendliness. (3) Increase the step rate of /D1 but not of /D0. Seems that the step rate is in CCDISK and applies to all drives, whereas the number of tracks is in the device descriptor tables and can be individually adjusted. mike k

#R:ihnss:-188500:uokvax:3500029:000:478 uokvax!emjej Jan 27 09:13:00 1984 Recent notes on CompuServe indicate that there's a fellow who has written a revised driver routine that will handle 35/40/80 track, single or double sided drives. Dunno about step rates, and I'd like to believe that he's done things right re looking the data up in the device descriptors, but it could be worth checking out. Alas, I know of no way to get the CCDISK module to do the right thing in that respect (treating each drive according to its nature). James Jones
