)WSID - Name the current workspace

When you begin using the APL interpreter, the Session Manager presents you with a blank screen, and your workspace has a blank name, it's known as a CLEAR WS. In order to be able to save your workspace, you must give it a name. You can do this without saving the workspace, by issuing a )WSID command followed by the workspace name. You can also name the workspace by doing the same thing with the )SAVE command.

Issuing the )WSID command without an argument lists the current name of the workspace. Otherwise it changes the name of the workspace to the argument and reports the prior name. Because a space is a value separator, you cannot give a workspace a name with spaces in it, the name will be chopped at the first space. Underlines may be used instead. Case is preserved on the WSID argument.

The command works like this:



)wsid big


)wsid hello there

WAS big


IS hello

)wsid x_5

WAS hello


IS x_5

)Wsid Mixed_Case

WAS x_5


IS Mixed_Case

The equivalent System Variable to allow a function to retrieve the workspace name is ⎕WSID.
