System Variable LX

⎕LX - Latent Expression

The ⎕LX variable is used within a workspace to set the action to take when the workspace is loaded. Typically it is set to the name of a function in the workspace. ⎕LX defaults to null.

Example usage:

⎕LX←'Start'

When this workspace is saved, the next time it is loaded, it will attempt to start the function Start. An error will occur if the function named in ⎕LX is not present when the workspace is loaded.

The function of ⎕LX is similar to the function of the AUTOEXEC.BAT file when DOS is started, or when in Windows if you have a shortcut in the Startup Folder in the Start Menu. The function or action in the ⎕LX system variable is executed before the Session Manager returns control to you.

Note that system commands beginning with a ) cannot be executed through ⎕LX.
