To make sure that you have no AutoCAD LT commands currently in progress before executing a menu macro, use the string ^C^C to begin the menu macro. This is the same as pressing ESC twice from the keyboard. Although a single ^C cancels most commands, ^C^C is required to return to the Command prompt from a DIM command. Therefore, ^C^C ensures that AutoCAD LT returns to the Command prompt in most circumstances before the menu macro continues.
