Display file DDS supports powerful ways to provide contextual help text to your users…but with limitations. Learn how to get around those limitations.

IBM supports a wide range of help-related keywords in DDS source—too many for me to cover here. If you have a free weekend (or three), you can browse through the latest Programming DDS for Display Files manual starting around page 123. Yes, I know the world is changing and in two (or five or ten) years, there will be no more display files. But then again, I've heard that since the mid-’90s, so forgive me if I'm not quite ready to roll up the 5250 just yet. And as long as we have green-screens, we should have good help text for them.
