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

== RSX ==
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.
