Re: Get/Set Refnum vs Global
The get/set refnum is what we refer to as a functional global. It stores data as a side-effect of its execution. It implements a name -> value lookup for some number of refnums of a given type.
Regular globals will work, but it will be more work to add one more sensor, one more motor, etc. With changes being made to the framework this year, it won't be as necessary to use either of these ... but that is for another day.
