| Abstract: | The basic algorithm for the conversion of decision tables into COBOL code is contained in the generator portion of the DETAB/65 preprocessor. The generator analyzes a decision table and produces simple COBOL conditional statements. Core storage is saved by using queueing techniques and extensive indexing and also by outputting the code as it is generated, a line at a time. The only optimization attempted is the elimination of obviously unnecessary tests on certain conditions in the decision table. Since the preprocessor and this language associated with it were developed for COBOL users, the preprocessor was written in a modular form in required COBOL-61. [ABSTRACT FROM AUTHOR] |
