The )LOAD Command
The )LOAD command loads the contents of a stored workspace from the tape
into the active workspace, completely replacing the contents that were in the
active workspace. When the command is successfully completed, LOADED
device/file number workspace ID is displayed.
Note: If the ATTN key is pressed during a load operation, the system operation
is interrupted and the active workspace is cleared.
Syntax
)LOAD device/file number workspace ID :Dassword
where:
device/file number is the number of the tape unit and the number of the file
on the tape.
workspace ID is the name of the stored workspace.
:password is the security password assigned to the stored workspace by a pre-
vious )WSID, )CONTINUE, or )SAVE command. If no password was pre-
viously assigned, a password cannot be specified. If a password was assigned
to the stored workspace but is not specified, or if it is incorrectly specified
for this command, the error message WS LOCKED is displayed.
The )MARK Command
The )MARK command formats the tape so that the active workspace or data
can be saved on it. Each )MARK command formats a certain number of files
to a specified size. Additional files of different sizes can be formatted by using
additional )MARK commands.
When the operation is successfully completed, MARKED
number of the last file marked size of the last file mar ked is displayed.
Notes:
1. The ATTN key is not operative during the )MARK command operation.
2. If the message ALREADY MARKED is displayed after a )MARK command
was issued, the specified file already exists on the tape. To re-mark the
specified file, enter GO. If the file is not to be re-marked, press EXECUTE
to continue.
CAUTION
If an existing file on tape is re-marked, the original information in the re-marked
file and the existing files following the re-marked file cannot be used again.
