|Insert 'No, because the ASCII values above "9" are ":", ";", "<", "=", ">", and "?" rather than "A" thru "F". To convert a nibble to hex, you need to add "A"-10 (55 or 0x37) if it is 10 (0x0A or 1010b) or more and "0" (48 or 0x30) if it is 9 (0x09 or 1001b) or less. Or you can add "0" as you suggest, then test to see if it is ":" or greater and then add 7 more ("A" - ":") if it is.' at: ''
