A 'hard value' as used by Pathagoras is simply the actual text of the selection that was made in response to an <<*Options*. . .>> or <<*AskOptions*. . .>> prompt (as opposed to the positional value of the answer.)  So if the prompt is <<*AskOptions(radio)*!Size!Small/Medium/Large/Custom*>>, and you choose medium, two 'answers' are recorded by Pathagoras: "2" for the positional value of the choice (which processes slightly faster) and "Medium" (the 'hard' value).
