This paper takes the programming language viewpoint of APL and assesses its functional capabilities with respect to the necessary requirements, in terms of programming language constructs, for writing structured programs.

A language extension, in the form of two new primitive functions, is defined so as to improve APL in this respect. The functions and their composition provide many interesting programming constructs, including the if-then-else.

Received May 1973. revised April 1974.
