Trac

TRAC is an early programming language designed for text manipulation on the IBM 700/7000 series. TRAC uses a simplified syntax for pattern matching and substitution, allowing users to specify how blocks of text should be transformed. It was developed in Bell Labs by Calvin Mooers in the late 1950s as part of his project on mathematical notation for human communication. TRAC's syntax inspired SNOBOL, a more widely known and influential string processing language that came out in the mid-1960s. While not used much today, TRAC remains historically significant for its role in shaping subsequent text manipulation languages and tools.
