Yes. And there are very few examples... I guess because it is a "tough one" Again my thanks to Scott.

So you want to extract the text constants that are displayed on the screen, then. You're right, you'll have to use QDFRTVFD for that. Unfortunately, this API is really difficult to use because it has about 10 million data structures, many of them are repeated as arrays, and many of them are variable-length. So, make sure you have a full bottle of aspirin ready to help with the headache that the API will give you. Here's an example of using that API... This isn't thoroughly tested, but it should work, and will (hopefully) give you the idea.
