BU-DDJ bug fix: As BU-DDJ was being keyed, a typing error apparently found its way into the C source code, viz. the user number range check has a multiply instead of an add. This makes it easy to receive an error message, as you can imagine. Not having a C compiler, I fixed the object code directly, learning much about the Aztec compiler in the process. If you're curious, I patched location 0376H from 'CD 79 43' to '19 00 00' (from a call to the multiply routine, to an ADD). I have tested the fix, and it apparently works ok. Caveat emptor, however. If you would like to change the source and recompile it, you would be doing all a favor. There is also a bug in the copying of a file to the backup disk when the backup disk is exactly full with the -H option, and a minor glitch when it protects split files. Try backing up a hard disk, and you may reproduce these errors. It is to BU's credit that the problems are easily gotten around, however. I have been waiting for this utility since it appeared in the Jan '85 issue of Doctor Dobb's (I don't have a C compiler, remember?), and can testify to its usefulness. It beats any other public domain backup utility I have seen, hands down. Try it! Thanks to Ian Ashdown for writing & distributing it, and to D.L. Finley to typing & compiling it.
