The )CLEAR Command
The )CLEAR command clears the active workspace. A cleared workspace has
no valid name and contains no user-defined variables or functions and no data.
The workspace attributes are set to:
I ndex origin
Workspace identification
Comparison tolerance
Printing width
Printing precision
Random number seed
Data

Symbols

1E 13

When the command is successfully completed, CLEAR WS is displayed.
Syntax
)CLEAR
There are no parameters.
The )CONTINUE Command
The )CONTI NUE command, using the specified workspace I D, stores the contents
of the active workspace onto tape without changing the active workspace. Primarily,
this command stores active status, such as suspended functions, so an operation can
be resumed later on the same or a similar machine. When the command is
successfully completed, CONTINUED device/file number workspace ID is displayed.
The )CONTI NUE command on the 5100 is similar in function and format to the
)SAVE command (except as noted below) and is distinguished from the )CONTI NUE
command on IBM APLSV.
Notes:
1. A clear workspace cannot be written on tape.
2. A workspace with suspended functions can only be written on tape using the
)CONTINUE command (it cannot be written to tape using the )SAVE com-
mand).
3.
4.
5.
)COPV and )PCOPV commands cannot specify stored workspaces that were
written on tape using the )CONTINUE command.
A stored workspace written to tape using the )CONTINUE command cannot be
loaded
into a 5100 active workspace that is smaller than the original active
workspace.
If a stored workspace that was written to tape using the )CONTINUE command
is loaded into another 5100 with a larger active workspace, the workspace
available (see the DWA system variable in Chapter 5) is the same as when the
workspace was written to tape.
6. If ATTN is pressed during a )CONTINUE operation, the system operation is
interrupted and the file is set to unused.
