We don't want to just beat a dead horse, but for one more swing:

"PRIVATE ALL" works and is the same number of commands as a "LOCAL loRecord", however it also hides EVERYTHING else, that may have been useful or needed in this routine somewhere. It's kinda like saying a sledgehammer works as well as the door handle... for opening the door. Sure, but maybe we wanted some of that door to still be there after we walked through!
