[Coco] DECB and BACKUP

[Arthur Flexser]

There are ways to modify the BACKUP command to do what you want, but they
require some knowledge of 6809 coding and the inner workings of Basic.  So
if you need to return to Basic, you probably want to avoid using BACKUP.

A wildcard COPY utility might be suitable for what you want, if it wouldn't
be incompatible with CoCoSDC use.  One such (WCOPY.BIN) is included on the
Extended ADOS-3 disk, available in the list archives.  It modifies the COPY
command to allow COPY *.* to <destination drive number>, returning control
to Basic on completion.  It possibly requires booting up (un-Extended)
ADOS-3 first.

If that would be incompatible with the CoCoSDC, then your best bet would
probably be a sector-by-sector copy using DSKI$ and DSKO$, or repeated
calls to DSKCON to do the equivalent.  It would be substantially slower
than the BACKUP command, though.
