The April, 1971, Data Base Task Group Report has already had a profound impact on the data base management community. At least five currently released systems claim to follow the report's guidelines. Yet the report was criticized at the time of its release for the lack of data independence in the Data Manipulation Language and excessive bookkeeping required of an application programmer. This paper demonstrates the use of a macro pre-processor which can increase data independence and greatly alleviate many of these shortcomings.
