True, this is a characteristic of RAD environments...but isn't there a better way? Runtime-driven development represents a step in the right direction. This article talks about Enable Runtime Explorer (Rex) and shows how a new development cycle can benefit the daily activities of PowerBuilder developers. Enable Runtime Explorer Rex is a tool for developers that implements the runtime-driven development cycle (see Figure 1). There are three components: Runtime Engine: This runs together with the application so that it can be explored in runtime, enabling errors/improvements to be identified and layouts/properties/scripts to be changed as a consequence Rex IDE: This allows the developer t...
