    Subroutine and function have same defination, throughout all tools these can't be differenciated based on tool.



    Subroutine is a piece of reusable code that doesn't return anything to caller.



    Function is a piece of reusable code that returns something to caller.

    Function can return any thing like Variant, Array, Object etc. If the function returns an object, as caller end function is assinged to a variable using Set.



    E.g.

    If Function F1 retuns an object.

    Function F2

    Set var1=F1(Arg List)

    End Function
