 *			byte 2-n text for position in byte 1
 *			byte n+1 another bit position
 *			byte n+2-m text for position in byte n+1

 *
 *		Eg. - "\020\001DOG\002CAT\003PIG"
 *		Print the bitmask in hex.
 *		If bit 1 (0x0001) is set print "<DOG>"
 *		If bit 2 (0x0002) is set print "<CAT>"
 *		If bit 3 (0x0004) is set print "<PIG>"
 *		If bit 4 (0x0008) is set nothing is printed.
