See Also: SAVE, LOAD, DELETE, LIST, NEW, RENUM PURPOSE: Sets and cancels passwords. REMARKS: Passwords are used to protect programs from listing or editing by unauthorized users. A password consists of a character string that is no more than 8 characters long. The 8 characters must be alphanumeric characters or symbols. The character string cannot be a null string. Once a PASS command has been given, the programs in memory are protected. A program protected by a password cannot be examined or modified in memory. It cannot be saved to tape or disk, or listed with LIST or LLiST. Nor is it possible to add or delete program lines. The only way to remove this protection is to execute another PASS command with the same password. If a password is set in the program to be loaded, that password is also set within the Card. If not, no password is set within the Card. If PASS is executed when no program is in the Card, an error occurs and no password is set. A password-protected program is protected against the NEW or DELETE command as well. Press IENTER I immediately after the password. Writing characters or symbols after the password results in an error and the password cannot be canceled. Example: PASS "ABCDEFG":A = 123 IENTER I ~ An error occurs. EXAMPLE: PASS"SECRET·IEN~RI Establishes the password ·SECRET" for the program in memory. 191

PURPOSE:

REMARKS:
Passwords are used to protect programs from listing
or
editing by
unauthorized users. A password consists of a character string that is
no more than 8 characters long. The 8 characters must
be
alphanumeric characters or symbols. The character string cannot be a
null string.
Once a PASS command has been given, the programs in memory are
protected. A program protected by a password cannot be examined
or
modified
in
memory. It cannot
be
saved to tape or disk,
or
listed with
LIST
or
LLiST.
Nor
is
it
possible to add
or
delete program lines. The
only way to remove this protection is to execute another PASS
command with the same password.
If a password is set in the program to
be
loaded, that password is also
set within the Card. If not, no password is set within the Card.
If
PASS is executed when no program is in the Card, an error occurs
and no password is set.
A password-protected program is protected against the
NEW
or
DELETE command as well.
Press
I
ENTER
I
immediately after the password.
Writing characters
or
symbols after the password results in an error
and the password cannot
be
canceled.
Example:
PASS "ABCDEFG":A
=
123
I
ENTER
I

An error occurs.
EXAMPLE:
PASS"SECRET·IEN~RI
Establishes the password ·SECRET" for the program in memory.
