When you exit the editor, FMSLogo loads the revised definitions and modifies the workspace accordingly. Multiple edit sessions are supported, but be careful of having multiple edit sessions that include the same definition. The final editor that is exited (and saved) takes precedence. Also realize if you delete procedures, property lists, or names while in the editor, then they are erased (see ERASE) from the workspace at the time of exiting (and saving) the edit session you deleted them from.
