System Productivity Facility

by P. H. Joslin
This paper discusses the purpose and design of a program called the System Productivity Facility (SPF). Perspective is provided by means of a brief summary of the earlier Structured Programming Facility (also termed SPF) and the requirements that led to a transformation of the earlier program into a new cross-system dialog manager. The new control facilities are explained to illustrate how the dialog manager supports a wide variety of interactive applications. Ways in which application development is simplified in the areas of data handling and display processing are explored. The purpose of the new table and file tailoring services is explained, and the error recovery philosophy is described.
