#I'm not completely sure what you are trying to show here. ?x
#means the
#character code for the letter x. This has nothing to do with the
#variable x. (That's not an issue because you're naming your variables
#better than that, right? :D)
in prgg, one generally does not know what is contained in x (otherwise, one
would not have to ask for it); so, how does one know what char (code) is in
x?
i only showed that
?x will not work, but
x[0] will

#No, there's not. See Integer#chr.
i was looking for the other way around, like Chr#integer.
thanks james and kind regards -botp
