Hello,
If you create a sub that takes its input from a global variable then you

correctness.
2. Higher error probability since you have t

One of the answers could be reusability and modularity. If you use
arguments, you can call this subroutine whenever you like and from different
programs too and not be dependent on the main program to define gl
