It was also wrong in the new version; will fix. >Despite the faulty READ_CAPACITY command, I must congradulate the author of >BTNTape (Mr. Rethemeyer?)

Very little of this stuff is adequately documented. I started out on this project knowing ZIP. >ensuring my tape system is stable, my next project will be to get QuarterBack >to use it. Any ideas? Yes. Ask QB to add BTNtape support :-) I'm only half joking. QB wants to use Exec devices, and does OpenDevice() and DoIO() calls. Since BTN is a DOS device, QB would need to do Open() and Write()/Read() from dos.library. To support QB as it is now, you would have to write a tape.device, and that's a whole area I haven't gotten into yet (and don't feel like getting into). I may write CCS to ask how hard it would be to support BTN. Meanwhile, TAR does quite well. The only thing about QB I miss is the nice interface. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bob Rethemeyer // "My Sneaker-Phone keeps kicking my DrBob@cup.portal.com -or- // Football-Phone off the hook." ..!sun!portal!cup.portal.com!DrBob // - Jay Leno
