Summary

Important Observations

• Special field handlers can do F4 type prompting very easily.  The results usually look better, work faster,  and place less load on your 5250  server.
• Special field handlers can do a lot more than F4 prompting because they allow you to attach behaviors to fields on your 5250 forms in many ways and at many levels.
• Application tracing is the tool you should use to debug handler issues
• If you write down a list of all  the "key" and "code" fields in your 5250 application and use a judicious field naming standard, you can automatically attach a prompting capability to all your 5250 screens.
