ATTRIB
lets you change the passwords to an existing file. Passwords are
initially assigned when the file is created. At that time, the update and access
words are set to the same value (either the password you specified or a blank
password). See Chapter I for details on access and update passwords.
Examples
ATTRIB DATAFILE ACC=JULY14, UPD=MOUSE, PROT=READ
Sets the access password to
JULY14
and the update password to
MOUSE.
