Comments on the implementation of recursive procedures and blocks in ALGOL 60

Abstract : Because of the importance, from the theoretical point of view, of recursive functions and because of the growing extent and irection of application of recursion in programming research and experimental mathematics, it is worth some effort to implement recursion - given that the costs in compilation and storage requirements are not too great. The mechanism for treating recursive procedures described here is such that the costs in time and storage to procedures involved in recursion are no more than necessary for a completely general recursion mechanism for ALGOL 60.
