Call

The Call statement is used to invoke a function or subroutine. You are not required to use this statement which invoking a subroutine or function, but it can make your code easier to read in some cases.

Another instance where you might like to use the Call statement is when you call a subroutine like a function. Normally, a subroutine call does not require parentheses around the parameters. If you wish to use parentheses, then you should invoke the subroutine with the Call statement.
