Focal Manual for CAI Coding on the TSS/8 System,
H. Dewey Kribs, Betty Wright, Edna C. Reynolds · 1970
Abstract : The document is intended to provide the basic information needed for coding CAI applications in the language FOCAL (Formulating On-Line Calculations in Algebraic Language). This language is available on the Digital Equipment Corporation Time-Sharing 8 System. While FOCAL is oriented toward solution of algebraic problems it is flexible enough to be used as a CAI coding tool. This document provides explanations and examples of those features in FOCAL most obviously useful for CAI coding. The document also provides information needed for utilizing the time-sharing system on which FOCAL operates. Since this manual could not demonstrate all possible coding techniques or anticipate all possible applications, the reader is also directed to more comprehensive sources. (Author)
