Details

UNIX operating environments use the ASCII system, so the RANK function returns an integer representing the position of a character in the ASCII collating sequence. The argument x must represent a character in the ASCII collating sequence. x can also be a variable containing a nonprintable character. If the length of x is greater than 1, the function returns the rank of the first character in the string.
