It should not be too hard.  Since you have such a rock solid format,  
you can safely assume in your case, the last 2 digits are ints always,  
always 2 digits long.

Just find the string of chars you are interested in, and substring the  
last two.  Now you have a number (int) and you can use a little math  
to +1 to it.

The only area you have to be careful in, depending on the language, is  
01 to 09 where the leading zero is going to get lost.  You could use a  
string pad left function to put a zero in, or in this case, just check  
the string length, if it is one, concatenate a zero in front.
