Important Notice
The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.
Undo Command (Full Menus Only)
Use to reverse your most recent edit. Undo restores the
current line to its condition before the last change you
made. Once the cursor moves off the line QuickBASIC accepts
the edit and Undo has no affect.
