GIGO* gets a punch in the "snoot" from the computer's error-checking system for trying to sneak "garbage" into SP data-gathering programs. The computer can detect and reject many kinds of "garbage," such as wrong dates and car numbers. But even these safeguards are not enough to protect vital SP programs against GIGO's efforts to slip in "goofed-up" data. Don't let this pesky little "bug" sneak anything past you! (*GIGO's name stands for "Garbage in; Garbage out," meaning you can't expect useful production from a computer if you feed it worthless information.)
