* If "string" = "", then a run-time error occurs.
* The value returned is in the range 0 to 255.
* The length of a string in bytes may be greater than or equal to the number of actual characters in the string.
* Use Asc("y") = x rather than Chr(y) = x
* Use IsCharAlphaNumeric instead of Asc() ?
* The value returned is in the range -32768 - 32767 for double byte character sets.
* VBA for Macintosh does not support Unicode Strings.
* You can use the ASCB function to return the first byte.
* You can use the ASCW function to return the Unicode number for the first character in a text string.
* You can use the CHR function to return the character with the corresponding ASCII / ANSI number.
* You can use the CHRW function to return the character with the corresponding Unicode number.
