Hex Plugin for REALbasic is a small plugin with four methods. You can give the plugin a string containing an unsigned decimal integer of essentially unlimited length and the plugin will give back a string containing the hexadecimal equivalent of that integer. And you can do the reverse. Also you can give the plugin a UTF8 or UTF16 encoded string, and the plugin will give back a string containing the hex representation of that input string. And you can do the reverse.
