MSE is a type-in program checker for machine-language Commodore programs used by the German 64'er magazine.

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.
