EDITING/EXECUTING METHOD FOR GRAPHIC FORMULA EXPRESSION FUNCTION TYPE PROGRAM

摘要

PURPOSE:To attain an editing/executing method of a graphic formula expression function type program that is suited to improve the program development/ maintenance efficiency by visualizing a function type program for improvement of the software productivity. CONSTITUTION:The syntax rules 105 and 106, the execution rules 109 and 110, and an inter-expression mutual conversion rule 111 are defined to both text form and graphic formula expressions of the function type programs. Then a function 112 is provided interactively edit the programs using those defined rules together with a function 114 which expresses the execution of a program as the transformation of the program expression, and a function 113 which performs the mutual conversion of both expression forms.
