Customers around the globe that are using version 10.3 have provided their view of the top features. If you haven’t installed D3 10.3 yet, here’s what you’ve been missing:

Enhanced Security and Performance
Installing D3 10.3 ensures that you have the most current features to secure your data and provide improved performance. This includes compatibility with devices, applications, and third-party products that work with D3.

Expanded list-locks Command Functionality
Expanded functionality includes modified output and enhanced BASIC to support up to 992 BASIC locks, increased from the previous limit of 64 locks. The list-locks command also has the following added options:

The set-tapefile command creates a dynamically defined pseudo tape; a transient assignment that disappears on system shutdown and restart.

The enhanced dev-make command allows assignment of a specific tape device number.

The mvWorkstation provides and manages terminal devices, serial printers, Windows printers, and Telnet Clients.Great for attaching local printers and terminals to remote or cloud-based servers.

    Although I am firmly connected with Linux versions, my long history with D3 and its predecessors broadens my interest in related versions. It also gives insight into what may appear in the next version that I am likely to use.

    Great to see the product moving forward with confidence.
