Looking for a fancy "requestor" - input thingy.

Though "PHI-prompt" supposedly supports this, I can't/don't understand how it is explained.

So: to confuse me more with other routines, I need help.

What I want to do is have a "list" of options, and using the up/down key, scroll through them until I press "Enter".

What I mean: I build a string which is something like: off,mon,tue,wed,thur,fri

Then on the screen, I get something that looks like:

What day do you want? xxxx

Where xxxx is one of the options from the string above. Pressing the up/down moves through the list and pressing enter selects the entry.

Dunno if there is an easier way or not. I am open to suggestions.
