CHARLIST()

Syntax:     CHARLIST(<expC>)

Arguments:  <expC> is the string to be processed.

Returns:    A character string.
            A list in which all the characters appearing in <expC> occur
            only once.

Usage:      This function can be used to determine a list of characters
            appearing in the >expC> string.  Each character will only be
            contained in this list once.  This can be used for instance,
            when encoding strings with the aid of characters.

Notes:      CHARLIST() supplies a maximum of a 256 character long
            string, which contains each character from <expC> exactly
            once.  This will produce an increasing list of symbols.

Library:    CT1.LIB
