The Message Window shows up only after there is something to display, so it may not appear when OOF starts up. If needed, there are Scroll Bars along the right and bottom edges. The Clear button removes all messages in the window. The Font pop-up menu and Size control allow you to change the appearance of the text. The color of the text in the Message Window indicates the type of message.
Blue commands indicate what function is being executed.
Black data is the output from the commands, while brown information is output that is incidental to the action of the command. Error messages are red, naturally.
