Generating sequence number

I am working on a Cobal program. please help me.

1.Each time it checks for a key ex:123456 and if its status is 'Z' for the corresponding key it generates a 6 byte char like A00001.

2.My problem is how to write a program such that when this generated number reaches max i.e A99999 it shud be incremented to B00001, and when B99999 it shud be incremented to C00001 so forth.

Can any one please give me the pseudo code or help me.

I did something very similar to this years ago, but I added the restriction of not using the letters I and O since they could be mistaken for the numbers 1 and 0. I used the other 24 letters of the alphabet. When I reached 99999, I searched a 24 occurrence internal table to locate the current letter of the alphabet. When I found it, I incremented the index by 1, used that occurrence as the leading character of the 6 byte key, and set the new 5 character number to 00000. Hope that helps.
