I need help for my homework for Visual Basic Studio.

1. What is wrong with this sub routine definition? Sub mySub(ByValue intNew as Integer)

2. Write the Sub prototype for a procedure which is named MyData and has first parameter as a string which can be changed and second parameter of an integer which can not be changed.

3. Write a sub-routine called 'DoubleIt' which will double any Long passed to it. Should be three statements.

4. Which event procedure is most often used to initialize variables and/or controls when a form is first loaded?
