The ALGOL 68 compiler of Paris-XI University (Orsay)

The ALGOL-68 compiler of the University of Paris-XI (Orsay) has been implemented for Univac's 1110-series, under EXEC-VIII. It can compile the “full language” (including formats, unions, flexible arrays, recursive modes, parallel computation, etc.). It consists in 8 passes and yields usual relocatable code. Minor restrictions concern equivalence recognition of crossed recursive modes, multiple precision and short modes, and scope checking.
