- ;* AESFAST Public Domain GEM bindings.
- ;* Maintenance:
- ;* 04/07/89 v1.2: This source file is new with this version.
- ;* Also, the calculation of the location of the prompt on the
- ;* screen has been changed. It was placed one boxchar height
- ;* down on the screen, putting it right below the menu bar.
- ;* This didn't look too good on a big-monitor system, so now
- ;* it is calculated by centering the box, then subtracting a
- ;* fixed offset from the centered Y to make it appear right
- ;* above the fsel'er box. The offset is 9 character heights,
- ;* (plus 2 extra char heights for the prompt itself), less
- ;* 2 pixels (just to line everything up real neat).
