I probably typed in 200 or more BASIC Programs and several machine language programs and only very rarely ran into a problem. Definitely never hit a checksum issue in MLX - I think that's what you meant when you said MSX? http://en.wikipedia.org/wiki/MLX_(software) http://en.wikipedia.org/wiki/MLX_(software) I was on a Commodore 64 using Compute!'s Gazette so maybe they had higher quality standards than Compute!?
