This was originally published and included with Commodore Disk User magazine, issue 14, vol. 3, no. 2, December 1989, p. 15 and Your Commodore, September 1990.
It was re-released in a new version by Logyk Software in 1993 and published with Commodore Format magazine, issue 37, October 1993, p. 9 as a disk bonus.
Commodore Format came with tapes, not disks so I guess that makes it a tape bonus rather than a disk bonus.
