#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
