Generic Data Transaction System. Version 2. System Design

摘要

This report and its companion (HFL-79-3/NPRDC-79-2) supersede HFL-78-2/NPRDC-78-2, documenting an enhanced version of the same system. The program described is a machine dependent, table driven, general software system written for the advanced programmer to communicate the internal operations of the software. Included are a description of data structures, program logic, and user interfaces. The Fortran IV software processes randomly accessed data which are tree structured by file, record, page, and field, and includes a functionally complete primitive command language, a display format processor, and provision for user supplied software appendages.
