doubt in report

I have to develop a report which is used to drive 3 sapscript forms.The 3 sapscript driver programs are created as 3 separate report programs.Now i should combine all this 3 report programs in my single report.In the selection screen of my report i will provide 3 radio buttons for each sapscript report program.when i choose one among of those radiobuttons and click execute,the corresponding report program should be run.How to proceed abt this.can any give sample code on this.

Thanks.
