Abstract:

For an extended data management system with information storage and retrieval capabilities a language is needed by which a user of the system can specify the records he wishes to retrieve and the operations he wishes to perform on these records. The Command and Query Language under discussion was developed to meet these needs for the extended data management system. Its development was divided into two spheres of responsibility. The first sphere, referred to as the Assembler, centers on the routines needed for accepting and translating user requests. The second sphere centers on those routines needed for executing the translated requests. These routines are called collectively the Interpreter. The design and implementation of the Interpreter is the topic of this thesis. This design and implementation includes routines to set up and change TSOS procedure files on the one hand and routines to service new TSOS Commands on the other hand. Author
