Sounds like the old "save with replace" bug, now incontrovertibly demonstrated
to exist. Don't EVER use the @filename notation in a SAVE statement: purge the
file separately first. Also, unless you have REL or USR files on the disk,
validate it after each few file purges. Make sure you never run your disks out
of space, and if you wind up with any "*" files, do a

		OPEN 8,8,8,"filename,type,M:CLOSE8

and a validate as soon as possible.

Never lost a file yet...
