  EVEN THE MOST STABLE OF US GET A.LITTL
E WEIRD WHILE PROGRAMMING..SETTING UP CO
MPLICATED ALGORITHMS,.JUGGLING VARIABLES
, TAKING CARE OF.NIT-PICKING DETAILS CAN
 BE STRESSFUL...  THE MOST COMMON SYMPTO
M IS A SORT.OF MILD PARANOIA -- A RELIAB
LE SOURCE.TELLS US THAT HE ONCE KEPT HIS
 DISK.LIBRARY HIDDEN IN HIS KITCHEN.CUPB
OARD, LODGED BEHIND THE SUGAR AND.BISQUI
CK...  THERE'S A BETTER WAY TO PROTECT.P
ROGRAMS FROM PRYING EYES  -- AFTER.ALL, 
EVEN A 1571 CAN'T READ A DISK.COVERED WI
TH MAPLE SYRUP AND CRISCO...  PROGRAM SE
NTRY PROVIDES A PASSWORD.SECURITY SYSTEM

EN YOU PRESS RETURN, SENTRY WILL.PROMPT 
YOU TO ENTER WHAT WILL BE THE.PROGRAM'S 
PASSWORD.  THE PASSWORD CAN.BE ANY LENGT
H.  (ONLY THE FIRST SIX.LETTERS ARE READ
