Post $PROMPT()$ macro Reply with quote
When does the eval of $PROMPT()$ macros happen? At the beginning of the snippet (before everything else) or when the snippet execution comes to that part? Is it possible to populate the list of choices for a prompted option with the results of a $$...$$?

I'm not sure if "at the beginning" is a technically correct answer, I think the engine evaluates macros referenced in the snippet code that it needs to execute, aggregates them as not to prompt for the same things multiple times, and then decides which prompts and in which order it needs to display. I don't believe that $PROMPT...$ or any other macro supports dynamic parameters by design as it would require multiple passes when evaluating the snippet code, which I don't believe it's designed for.

I was afraid the answer was going to be something like that. Dynamically assembled $PROMPT$ choices could be a powerful feature, kind of a user-defined popup. Would you be so kind and ask the teams opinion on that, please? I'd like to know what they think about it.
