 Obfuscation in this entry consists of:

 * Detection of whether to print the ASCII or EBCDIC values is done by taking the
 remainder of dividing the character `'J'` by `2` - the ASCII value of the
 character is even, the EBCDIC value is odd.

 * The trigraphs are not there as obfuscation nor are they there to annoy the
 judges - it's just the easiest way to get around the absence of square brackets
 in a normal 3270 environment.
