Que about smartform::::

Good Noon to my all ABAP Gurus And Gurumaiyas....

Here once again i came here to give some silly questions ( may be for u...)

" Could anyone tell me basics about smartforms executions i mean how does it execute??? How can i use two pages in smartforms??? What is need of loop in smart form??? and why, when and how can i use it??? "

I know basics about smartforms and i have also implemeneted it.... but i m not much aware of it.....i would be thankful to u if u take out 15 mins from ur busy schedule....

Waiting for ur reply.....

Warm Regards,
