Abstract
A change to the scope rules made popular by Algol-60 is proposed which provides facilities similar to a Modula-2 module or and Ada package with no increased complexity over the original Algol scheme. Also, own variables become superfluous, as a facility very like them is an automatic byproduct of the modification. Implementation issues are discussed and a description is given of a run-time storage allocation system similar to an existing storage scheme for Algol-60.Keywords
