Commodore 1581 - DCLEAR Command

DCLEAR
One command that should not often be needed on the 1581, but
is still of occasional value is DCLEAR. On the 1581, and nearly all other
Commodore drives, this function is performed automatically, when
ever a new diskette is inserted.
The result of an DCLEAR, whether forced by a command, or done
automatically by the disk, is a re-reading of the current diskette's BAM
into a disk buffer. This information must always be correct in order for
the disk to store new files properly. However, since the chore is
handled automatically, the only time you'd need to use the command
is if something happened to make the information in the drive buffers
unreliable.
FORMAT FOR THE DCLEAR COMMAND

EXAMPLE:

or it may be abbreviated to
