TRAC

Designed by: Calvin Mooers

TRAC (for Text Reckoning And Compiling) Language is a programming language developed between 1959–1964 by Calvin Mooers and first implemented on the PDP-1 in 1964 by L.

Peter Deutsch.

It was one of three “first languages” recommended by Ted Nelson in Computer Lib.

TRAC T64 was used until at least 1984, when Mooers updated it to TRAC T84.
