THUMB SYSTEM

an auditor trick that permits better attention on pcs' answers and less command mistakes on alternate command processes, when you give the plus command put your thumb on your index finger. Hold it there until it is answered. When the minus command is given, put your thumb on the second fingertip until it is answered. This sets up a physical universe tally and keeps one from mucking up the command sequence without having to "hold it in mind." This permits better observation of the pc. (HCOB 1 Sept 60)
