Create text lines with number increment +1

I have some text lines I need to generate about 1000 of each. In these text lines there are some numbers connected with text (numbers not seperate). In each new line some of the numbers in the text lines must increase by 1 (but not all the numbers). Must be delivered in txt format. See example: ------------------------------------------------------------------ XXXAb281 BT284 Great River D1 6#45 A2165 Will stay B2333 XXXAb282 BT284 Great River D2 6#46 A2166 Will stay B2333 XXXAb283 BT284 Great River D3 6#47 A2167 Will stay B2333 ---------------------------------------------------------------- This continues for 1000 repitions of the lines where some of the numbers increase. As you can see some numbers increase but others do not. I have 3 sets of these with variations that I need in seperate txt files. Actual txt files can be delivered in PM if you are considering a bid, but not sure if you are able to do the job. I am not sure if it is possible to arrange this for a modest price, but I believe there are some text editors that may be of help to do the job easy for a skilled user using an advanced copy and paste function.
