PACT (compiler)
PACT was a series of compilers for the IBM 701 and IBM 704 scientific computers. Their development was conducted jointly by IBM and a committee of customers starting in 1954. PACT I was developed for the 701, and PACT IA for the 704. The emphasis in that early generation of compilers was minimization of the memory footprint, because memory was a very expensive resource at the time. The word "compiler" was not in widespread use at the time, so most of the 1956 papers described it as an " coding system", although the word compiler was also used in some papers.
