The return value is
a character string that contains the binary representation of the
address. To display this value, use the $HEX
w. format to convert the binary value to its hexadecimal equivalent.
If you store the result in a variable, that variable should be a character
variable with a length of at least eight characters for portability.
If you assign the result to a variable that does not yet have a length
defined, that variable is given a length of 20 characters.
