Hi All,

           Sorry if I am not clear with my requirement, Let me try to 
explain in detail...
I have to create few Accounts, so the account number i am providing to 
the system manually each time and it should be in series.
I have to enter the 7 digit account numbers in two text box in my 
application.
the First 3 digits goes in first text box and remaining 4 digits goes in 
the second text box, that is why i was looking for a Split function.

eg:  Default or starting Account No - 1230567, so next one in series 
should be 1230568,1230569....so on. I need to increment this account 
number everytime, so that my code picks the next correct number.
Secondly, i have to place these account numbers in two different text 
boxes.
first 3 digits, ie 123 goes into first text box
remaining 4 digits goes into second text box.

Increment and Splitting the numbers in my code, the better way i was 
looking for....
Let me know if you require more information.

Cheers
