The )ERASE command erases or deletes the named function(s) or variable(s) in the current workspace. The workspace is not changed on disk unless you )SAVE the workspace. Once a variable or function is )ERASEd it is no longer defined. Attempting to erase a non-existent function or variable returns an error message. )ERASE with no arguments has no effect; to erase everything in the workspace, use the )CLEAR command to start a fresh, clear workspace.
