there are many ways to do it
depending on what all your wanting this to do, i'd probly recomend hash tables, or if u dont know hash perhaps ini files.
although ini files are for more perminat values realy ..
if i read your question right u dont mean input as in like an on input event, but rather a script that asks for input from the end user, useing perhaps $$?="" or $input() or a custom dialog?
if so just set these values up in a hash table, in there own varables, or in an ini file
and you will be able to refrence the values again later
or if your just doing somethign extreamly simple..
set %input.nick $$?="Enter your nick"
set %input.age $$?="Enter your age"
set %input.color $$?="Enter your fav color"
its hard for me to answer your question specificly without knowing more information about what your trying.
hope this was helpful, if not please re explain wiht more detail
