From the documentation:

This Algol 60 interpreter is based upon the "Revised Report on the Algorithmic Language Algol 60" [RRA60].

At school, a long time ago, I learned Algol 60 in a completely theoretical manner. Later I learned Algol 68 and C (and more ...).

The concept of call-by-name never left my mind, and so I started to write this Algol 60 interpreter: Made for fun and a call-by-name.
