BASH_ARGV is a special built-in variable. It's an array of the command line arguments. More specifically, the man page says it's the arguments located on the stack. So it's safe to read them, but I strongly suggest not modifying them. To access the array, use [X] to refer to a specific argument. The arguments are put on the stack "backwards" and explains why the last argument is indexed with 0. Lastly, BASH_ARGV will change inside a function call (because the stack changes). So be careful where/how you access the variable.
