Identifies characters used in the hexadecimal representation of a numeric value.
IdHexDigits: array [0..15] of AnsiChar = ('0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F');
IdHexDigits is a constant array containing valid characters that can be used in the hexadecimal representation of a numeric value. IdHexDigits characters can be accessed by an index value that corresponds to the decimal value for the hexadecimal character.
IdHexDigits is used in the ByteToHex function to access the string representation for each nibble in the byte.
