Abstract :
An existing highly functional relay settings card file containing a vast amount of technical data for a large variety of relaying terminals was computerized. The primary goal was to retain the transparency of the existing manual file while benefiting from computerization´s handling capabilities. The computer´s limited ability to use preprinted output forms was overcome by programming it to create its own forms. Efficient programming and data organization resulted in the computer displaying and printing forms similar to those used in the manual file. This made the new file as convenient as the old and compatible with it over the 2 year transition period. The programming provides fast, interactive access to all records in the file and allows displaying and printing of a large variety of card forms and useful reports.
