Hi Deepak!!
Sub don't accept parentheses when we pass parameters.
Parentheses is used with function while passing parameters.
Hope this will help you
Cheers :)

You may use Call Keyword.
With Call:
Call MySub (parameter1, parameter2, ..., parameterN)
without Call:
MySub parameter1, parameter2, ..., parameterN

Hi Vinod
Thanks for your reply but as you said that sub don't accept parentheses, this is not completely true because if you use the 'CALL' keyword with sub, it will take parentheses.....
Good Day

Hi!
Assumend from MSDN:
You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function's return value is discarded.
To pass a whole array to a procedure, use the array name followed by empty parentheses.
