Getting Dates from Selection-option of type date

Hi Experts,

I have a requirement where I need to create a select-option for date as below.

select-options s_date for sy-datum.

I have to use this select option and pass each date to a function module. For example, if I give 01-Jan-08 and 10-Jan-08 in the low and high values of select options It need to loop through all the values from 01-Jan to 10-Jan and send it to the function module individually.

Please let me know whether there is any simple way to do this. In this it need to consider extensions as well. Like Single values multiple values, include exclude.

Thanks in advance.
