Difference between Using and Changing

18 Views

hi,

while defining subroutines, what is the exact difference between Using and Changing?

when we pass by reference we can use both and while passing using value we can use both + Value (VAR).

Then what is the exact difference between two?

Also, what is formal parameter?q
