Program driven applications

The third type of application is the most sophisticated. Superbase starts up, and starts running code that never ends until the program ends. During it's execution, the code is always running, unless the user is in data entry mode (commonly called ENTER mode in older apps) or the user has the cursor visible on the screen (also known as ENTER mode). During these times, Superbase temporarily stops executing the code and instead waits for the user interaction to occur. Once some predefined objective is met, Superbase passes control back to the code, and the code keeps executing.

It's important to note that in this type of program, the code is always looping, executing, doing something, or temporarily suspended inside of the ENTER command waiting for data entry to terminate. This is important because the ENTER mode of operation in the older style of Superbase is the SINGLE BIGGEST MENTAL BLOCK that people have with migrating applications forward, or maintaining existing ones. In a Superbase program driven application, the code is always executing, except during ENTER mode.

In version 3 applications, ENTER mode was superceeded with a new mode call Process() and process() was designed overcome all of the limitations of ENTER mode, while being partially backwards compatible with it.

In order to write a Multiple Windows Superbase application, you cannot use ENTER mode and instead must learn how to use Process() mode for a program driven application.
