6. Application example

The “Address Management” program shown on the following pages shows a typical application example for diskette processing with the LASER-DOS.

It allows the entry, storage and editing of up to 100 addresses.

The addresses are stored on the diskette in a “MAILBOX” file.

The processing procedure was selected with regard to the weaknesses of DOS BASIC 1.0 in such a way that when the program starts the file content is read completely into the memory and at the end of the processing it is written back completely to the diskette due to changes.
