PSE Summary

The PSE is evolutionary in terms of the computing resources used.
The PSE should allow incremental additions to the software resources of the environment.
As new numerical methods are developed it will be a simple matter to incorporate them into the software resources accessible by the PSE.
The PSE should feature not only complete applications, but also an application editor that allows a user to graphically modify an existing application, or to build a new application from scratch.
The application editor should be fully integrated with an on-line documentation system, and context-sensitive help.
