Description of the Book:

Some computers permit conventional programing languages to be extended by the use of macro-instructions, a sophisticated programing tool which is especially useful in writing instructional dialogs. Macro-instructions (or “macro’s”) are complex commands defined in terms of the machine language or other macro-instructions. Like terms in higher-order languages they can expand to a variable number of actual machine instructions. The system described here is based on the use of the macro-assembler of the Sigma-7 computer, called Metasymbol. Metasymbol allows for the use of machine language, the definition and use of macro-instructions, and the inclusion of FORTRAN subroutines. This system allows the teacher considerable flexibility in composing instructional dialogs. Specifics of programing are discussed, and an example computer run given. (RB
