Data Management System

(Recommended for ages 15 and up/Written in BASIC and machine language)

Here’s a data management system ideally suited for short records, such as record, tape, and book catalogs; telephone and address directories; and inventories. Menus and prompts guide you through all input activity. First, you define the characteristics of your file. You enter the file name, the number of fields (up to 8), the field headings (up to 11 characters), maximum field value (up to 30 characters), and the editing desired on a field’s value (none, numeric, date, or dollar edits). You can store records as large as 140 characters. From then on, you can add, update, and remove records. You can search your file on any field using whole or partial search keys. Valid search terms are less than or equal to, equal to, greater than or equal to, and range. You can display your search results on the video screen or print them on your printer (up to 130 characters), specifying either complete or partial records. Finally, you can sort your file on any field, specifying either ascending or descending ASCII values for characters in that field.

The authors invite questions and comments by telephone.


For a small data management system, this program is well designed and easy to use. Files remain on disk (ex- cept during sorts), making possible a fairly large base. The assembly language sort is fast. You can search on only one key at a time.

The user manual is VERY GOOD.
