1. General purpose language syntactically like RATFOR,

semantically like C. Lacks structures and pointers. Used

as a source language for Jack W. Davidson and Christopher

W. Fraser's peephole optimiser which inspired GCC RTL and

other optimisation ideas.

. It is a copy

of the original distribution from the University of Arizona

during the early 80's, totally unsupported.
