MOL-360 explained

MOL-360 is a mid-level systems programming language for the IBM System/360 family of computers based on Algol.^{[1] [2]}

The only data structure supported by the language is arrays. It has no support for floating point data, but allows direct access to processor registers and inline assembly language.

MOL-360 was used by System Development Corporation (SDC) to develop the ADEPT time-sharing system.^[3]

A similar language, MOL940, was written for the SDS 940 computer system.
