Passwords are used to protect programs from inspection or modification by other
users. A password consists of a character string no more than seven characters long.
The seven characters may be alphabetic or one of the followi n g special symbols:
'#$%&()*+-/,
:;<=>?@\.r-7T . . . . .
Note: Do not use any BASIC command or verb as a password.
Once a PASS command has been given, the programs in memory are protected. A
password-protected program cannot be examined or modified in memory. It cannot be
sent to tape or listed with LIST or LUST, nor is it possible to add or delete program
lines. I f several programs are in memory and PASS is entered, all programs in
memory are protected. The only way to remove this protection is to execute another
PASS command with the same password.
Note: When a password with more than seven characters is declared, onl y the first
seven characters are valid and are set or removed from pf.otection: ~· - ~ ,
