DiskDoctor is a new 1.2 CLI command and is on 1.2 WorkBench.  It attempts to
fix trashed disks.

1. No you can't assume that everything you download from a BB is an
   executable.  It could be source code, or uuencoded executable, or
   ARC'd executable, etc., etc.  We've had two different MEDs here.
   I think one was shar'd source, the other uuencoded executable.

2. If you DO Xmodem an execuatable from a BB, it will probably end up
   with Xmodem filler at the end.  I think Xmodem sends something like
   128 byte blocks, and pads the last partial block to 128 bytes.
   AmigaDOS rejects executables with extra trailing filler, so you
   need a program like the public domain "fixobj" to chop the filler
   off of it.

So you either downloaded something that was not an executable, or you've
got an executable with filler on the end.
