Compatible Time-Sharing System - Characteristics

Characteristics

• CTSS had one of the first computerized text formatting utilities, called RUNOFF.
• CTSS had one of the first inter-user messaging implementations, possibly inventing email.
• MIT Computation Center staff member Louis Pouzin created for CTSS a command called RUNCOM, which executed a list of commands contained in a file. (He later created a design for the Multics shell, which in turn inspired Unix shell scripts.) RUNCOM also allowed parameter substitution.
