$origin should not be included in the function definition. It may be used as an argument when calling a function or subroutine, but it should not be included in the definition of one. You should check the flag before calling the checked subroutine, because that will minimize the use of the subroutine. The same goes for checking the rank of the destination. Always do less expensive operations before more expensive operations, because that will minimize the need to do the most expensive operations.
