A MACRO SYSTEM FOR COMPUTER ASSISTED INSTRUCTION.

The macro system is implemented within the Coursewriter programming language. It is designed as a time saving system to eliminate the repetitive coding of general routines. These routines, consisting of a series of instructions originally developed to handle one particular problem or problem section, can, with little or no modification, be incorporated in other lessons or problems. Utilization of the macros is similar to that of a subroutine. The difference between them is that a subroutine is a self-contained unit which is separate from the main program, whereas, a macro consists of a set of frequently used instructions that are included in and dependent upon the normal flow of the main program.
