MSE by D. Weineck and N. Mann is a type-in program checker for machine-language Commodore programs used by the German 64'er and Happy Computer magazines.

To help readers by typewriting the program listings, at the begin of the year 1985 the little programming helpers MSE (Maschinenspracheeingabeeditor / Computer Code Editor / for Assembler-Listings) and Checksummer (Prüfsummenprogramm / to check the right BASIC-Codes) were published. In the next months the programming helpers were upgraded. Other German computer magazines published this helper-methods, too.

MSE v1.0 uses straight hex digits to enter data while MSE v2.0 uses all letters in a 4-digit letter-number combination, making for a smaller listing. MSE v2.1 corrects a small bug that could cause different lines to have the same checksum. All three MSE versions are incompatible with each other.
