Program for making business graphics from Digital Research. To run the application, place side A in drive A: and side B in drive B:.

The Amstrad version has a CP/M 3 RSX attached which modifies the program's behaviour:

BDOS function 2Dh is used to stop the program terminating if there is a disk error.
Input keycode 0FCh is translated to 1Bh (Escape) and 7Fh (Delete) is translated to 08h (Backspace).
The code which loads overlays searches for the overlay on drive M:, and then on A: or B: depending on the number of the overlay.
When files are being loaded from disk, BDOS function 2Ch is used to try and read as many records as possible in one go.
