TRAC (programming language)

（重定向自TRAC Language）

TRAC (for Text Reckoning And Compiling) Language is a programming language developed in the early 1960s by Calvin Mooers. It was one of three "first languages" recommended by Ted Nelson in Computer Lib.

TRAC is a purely text-based language—a kind of macro language. Unlike traditional ad hoc macro languages of the time, such as those found in assemblers, TRAC is well planned, consistent, and in many senses complete. It has explicit input and output operators, unlike the typical implicit I/O at the outermost macro level, which makes it simultaneously simpler and more versatile than older macro languages.
