Hi, it is posible with lingo to convert certain string into its
equivalent uppercase string, and also a way to convert a string to
lowercase.


Yes. My preferred method is to use offset:


on touppercase thetext
alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
repeat with a = 1 to the number of chars in thetext
c = offset(char a of thetext,alphabet)
if c > 0 then put char c of alphabet into char a of thetext
end repeat return thetext
end


on tolowercase thetext
alphabet = "abcdefghijklmnopqrstuvwxyz"
repeat with a = 1 to the number of chars in thetext
c = offset(char a of thetext,alphabet)
if c > 0 then put char c of alphabet into char a of thetext
end repeat return thetext
end



Some people get into using ASCII codes instead, but I think they're masochists.
