This is an NDA (New Desk Accessory) that puts a clock into the upper
right corner of the MenuBar, so it can't be covered by any open windows.
Once opened, you can click on a check box in the NDA window to show the
date, as well. It works with most GS specific programs that support NDAs,
with both 320 and 640 mode displays, though not many 320 programs have 
few enough menu items to prevent it from messing up the MenuBar. 
BarClock re-draws the MenuBar after it's closed, so you don't have to
worry about having the bar permanently messed up. To use BarClock, copy
the file BARCLOCKNDA to the DESK.ACCS subdirectory of your startup disk.
With TML Pascal source code and icon. In BQY format. Use BLU to extract.
