Your colleague has not used Visual Basic in a while and so when he encounters a decision point, he sometimes calls out to you over the cubicle wall to get answers to his questions. He wants help remembering which method of passing an argument will give the Sub procedure access to the value of the passed argument without actually referencing the variable declared in the calling procedure. Which of the following do you suggest to him?
A) ByVal
B) ByRef
C) ByArg
D) ByInd

Question

The ByVal keyword is used to pass a copy of the value of the argument, rather than a reference to the variable or object itself. This means that any changes made to the argument within the Sub procedure will not affect the original variable or object passed in the calling procedure. This is useful in situations where you want to protect the original data, or if the parameter represents a constant value that should not be changed.
