**User:** 4GL zoom.from sections

**Assistant:** The zoom.from section in 4GL defines the fields displayed when zooming from a particular field. It doesn't define what gets called when you click a zoom button, but rather what data is shown in the zoomed-to session. Think of it as configuring the link between two sessions. To understand what happens when you click a button (like the save button), you need to look at other sections of the code, such as choice.update.db or on.choice depending on the specific trigger. Debugging the code, as suggested in the forum thread you referenced, will be the most effective way to understand the exact flow of execution.
