The programming language Pascal was designed and implemented in a non‐interactive programming environment. This paper surveys proposals for incorporating interaction into Pascal, and focuses on a scheme known as ‘lazy evaluation’. It presents and compares performance measurements of two Pascal run‐time systems for the same compiler; a buffered, non‐interactive version, and a modification of that system to support lazy evaluation.
