Expert Solution
Step 1
Passing arguments in Visual Basic
- The arguments can be passed to procedures in visual basic either by value or by reference.
- In the procedure call, if an argument is passed by value then keyword ByVal is used in the procedure header that indicates a copy of the variable is passed and the receiving procedure can not modify that value.
- If the argument is passed by reference then keyword ByRef is used in the procedure header that indicates the actual variable is passed and therefore the receiving procedure can access or modify the variable value.
