Hmmmm... I *have* been using the @0: command on my old 1541 drive
since I have had it (four or five years now), and have NEVER had any
problems.  I also thought that a Commodore Representative posted a
message saying that as long as one specified the drive number (i.e.
the 0 in @0:) that the porblem would NOT occur; the problem only
occurred when one used '@:' (i.e. without specifiying which drive).
What is the official word on this (yet again), and could we have the
advice of someone who designed or knows a lot about the 1541?  I
repeat that I have never had any problems ever with the '@0:' command,
and have used it to an incredible extent (in games such as Elite, when
you want to resave your current pilot under the same name, just use
the old @0:, because you cannot delete the old file first!).

[My apologies to Eric Cotton if he was involved with the 1541 design,
or if he is quite knowledgable about 1541's; however, I am positive
that I read a message from a Commodore Rep. who said that the @0:
command worked fine _as_long_as_you_specified_the_0_]
