Um... mjordan, the doubling is included in my program.

Also, the printf("%1s\n",roman) does the following.

It prints the string, roman. However, since the length of the string is undetermined, I simply put a 1 before the call. That means that it will print the first character of the string. If there are any characters following that, it will print them as well.

The 1 can be removed if you like as there is a null character in the string. I had it in initially for testing purposes.

What is it they say about silence being golden?
