This feature helps developers save time and effort, as they can leverage these existing solutions instead of reinventing the wheel for every new project.
SheerPower 4GL and the Transition from OpenVMS to Windows
The transition from OpenVMS to Windows was a pivotal moment in the evolution of SheerPower 4GL. OpenVMS, which was originally developed by Digital Equipment Corporation (DEC), was a powerful operating system for its time, particularly in mission-critical applications. However, as the computing landscape shifted toward more widely used platforms like Windows, it became clear that a new version of Intouch 4GL would be necessary to keep pace with these changes.
The decision to port the Intouch 4GL to Windows gave birth to SheerPower 4GL, and the new language was designed with Windows developers in mind. This meant that SheerPower 4GL was able to take advantage of the graphical user interfaces (GUIs), networking capabilities, and other features that were native to Windows, making it easier for developers to create sophisticated applications.
Despite the differences between OpenVMS and Windows, the core principles of SheerPower 4GL remained unchanged. The language retained its high-level abstractions, simplicity, and database-centric features, all of which were highly valued by developers. The move to Windows also opened the door for a broader range of developers to experiment with SheerPower 4GL, leading to its use in a variety of industries, including finance, healthcare, and manufacturing.
