Just to see if they are defined, or do you make sure they are scalars, arrays, have the proper dimensions, etc? Is there a "too overboard"?

So, check all anticipated/potential errors, then include a CATCH for the ones you miss. When you discover one you missed, you put in another check. Is that the gist of it?
