private functions.

associate that function.i mean function code will be stored
in library files with .vbs xtension,before using this
function we should associate that function to our script.
private function:this is used only in the action where it
is created.(it will not work even in another actions of
same test)

Answer / bfakruddin

Function: Function is a block of statements which is used to
perform a particular task and we can call from any test and
pass parameters from calling function and get the result
from called function.

Function returns Single value, we can pass no.of input
parameters and get no.of output parameters and use that
output parameters in tests, But returned value would be on
function name, i.e. the return value at calling function
We can declare function in function

No need to explain about public and private functions in
interviews until unless they ask about the differences.
many interviews they ask differences between sub procedures
and function procedures.
