* "Olivier Pinçon" <opin...@wanadoo.fr> | How can I transform single characters (like 'A, 'B, 'C) in strings which | contain 1 character (respectively "A", "B", "C") ? | | Please tell it me !! It should'nt be complicated !!
'A, 'B, and 'C aren't characters, they are (quoted) symbols.
if you want a mapping from string to symbol, it's INTERN (creates it) or FIND-SYMBOL (looks it up, only). if you want a mapping from symbol to string, it's SYMBOL-NAME.
#\A, #\B, and #\C are characters. if you have a string of length one or a symbol whose symbol-name is a string of length one, CHARACTER will return the corresponding character.
(character 'a) => #\A
if you want to create a string out of a character, STRING will do that:
(string #\a) => "a"
which textbook or reference manual are you using?
[I have assumed Common Lisp in the absence of any contrary information.]
