Here is my code ... in function runtask i need to call my function Task_10,Task_20 or anyother according to the variable var.period so how can i call a function using a variable as a function name ??? .. here i have dome something but its giving error please help me in this concern soon.

You need to re-think your logic. I can't imagine why you'd need to do, what you're asking about doing.
