Previous month last date

Hi folks...

Is there any straight FM to get the last date of the previous month. For eg if current date is 04/30/2006 then i should get 03/31/2006. <b>NOT</b> 03/30/2006.

The same can be achieved by using 2 FM's. But I am looking for a single FM to suffice this requirement.

Early response is appreciated.

Regards,

Bhanu
