A Concept For a Primary Author's Language (PAL-X)
Ripota, Peter
A Primary Author's Language (PAL-X) has been developed to serve as a documentation language for computer-assisted instructional (CAI) programs. Its development was necessary to permit the dissemination of CAI given the facts that: 1)existing CAI programs were written in over 60 languages; 2)the system for COURSEWRITER II, the most commonly used language, was discontinued by International Business Machines (IBM); and 3)an exchange of programs was found to be nearly impossible. PAL-X was built to contain answer-processing functions, to be independent of hardware and of machine, programing or author languages, to have simple, internationally recognized symbls, and to be capable of partition into subsets. The language was designed to function with non-generative and generative CAI; operations, names and text were separated and the verbosity of programing languages avoided. It was constructed to be used for primary authoring of CAI, to date it has been employed to author CAI material at the University of Freiburg, to translate programs from COURSEWRITER to LIDIA, to introduce students to the principles of CAI, and to document a program in general chemistry.
