Enhancing the HP e3000 User Interface

4
4GL
4GL is available on the HP e3000 and provides an easy way to develop GUIs. Most 4GL
providers have migration paths for their existing users to move to the GUI interface, often with
client/server implementation. 4GLs can also allow users to integrate the power of the 4GL with
their legacy code. (Please see Appendix D for advanced 4GL products.)
Screen Intercept
Vendors are providing a way for a desktop process to run a terminal session. The desktop
program is able to retrieve and enter data on the pseudo terminal. Using this legacy interface
and mixing in other data sources, the user is presented with a refreshed and enhanced interface.
(Please see in Appendix E for products to provide screen intercept.)
Windows Applications
Applications also have been developed for the HP e3000 with a Windows user interface. These
applications make it easy to perform MPE/iX activities from a Windows-based interface. (Please
see Appendix F for a list of tools to create, edit, enhance or simplify HP e3000 applications from
a user-friendly Windows desktop.)
Summary
Many third-party products and tools exist to provide enhanced user interfaces and GUIs to
HP e3000 users. However, there is no single universal product or method that addresses all
concerns. The user's unique requirements should dictate the particular method or technology
chosen. HP encourages users to review the possibilities, and then follow up independently with
the individual third-party vendors.
