The ilem project: Pascal to algol in easy stages. I: Outward bound
A. N. Walker · Software Practice and Experience · 1986
Abstract Most academic institutions have Pascal compilers coming out of their ears. Most academic institutions have Algol compilers only on their dinosaur mainframes. The Ilem project consists of designing a sequence of intermediate languages, IL0, IL1, IL2, …, ILN–1, ILN, where IL0 is Pascal and ILN is Algol, and where any two consecutive languages differ so little that a one‐man spare‐time project suffices to convert a compiler for one language into a compiler for the next.
