Code reviews

This is a new string of articles that I will try to update every week or so.  This time I will be reviewing a code I made up myself:

You take your message and turn it in to morse code, then you take an invented number key in three parts (two for dash, one for dot) that is shared between you and your friend, say, 12,17,18,13,05,11 for dot; 19,10,06,02,01,09,23 for dash and 39,36,99,27,35 for dot again. You then make up a random key for punctuation, say, comma=//, full stop=OO and end message=(*) and (^)for next letter

The message army would therefore be: 12,19(^)39,23,11(^)06,09(^)01,12,01,02(*)
