Increment in date
Hi,

I have a variable lets say DATA_DATE.
I have to pass some value to this variable in YYYYMMDD format.

lets say today I have passed this variable as :

DATA_DATE=20100107

Then pls help me how to calculate another variable DATA_DATE1 (which is DATA_DATE+1).

The code should work properly in the end of month & end of year.


Many Thanks.
