Re: What's wrong with this code??

I figured that out after I sent the email. The reason I used the 0 in the first place was that I was having all sorts of problems with it - and it seemed to work fine for 01 to 05 so I just continued on with it - not even thinking about it. Your right though, the code is awkward - but I couldn't think of any other way of doing it. Any suggestions?

Prefixing a number with a zero makes the intepreter believe you're > using octal numbers. Oczal numbers range from 00 to 07, the decimal number > 8 would be 010 in octal notation.
