Breaking 0FISCYEAR into 4 quarters

Guys,

I have a task to create a report in which user will input a fiscal year. I need to take that fiscal year and append 001 to 003 to make it a first quarter. so fo example: If user inputs '2007' on the selection screen. I need to make it 2007001 through 2007003 so I can get data for first quarter of 2007. Can someone give me the code to do this?

Thanks,

RG.
