When the button is clicked, the program first initializes a variable "number" to 3. Then it calls the subroutine "DoubleAndSquare" and passes the variable "number" by reference. Inside the subroutine, the value of "number" is doubled (to 6) and then squared (to 36). Since the variable was passed by reference, this new value is also stored in the original variable "number". Finally, the program sets the text of a text box to the string representation of "number", which is "36". Therefore, the output will be "36".
