If you are using the SAS windowing environment and
you try to access a password-protected member without specifying the
correct password, you receive a dialog box that prompts you for the
appropriate password. The text that you enter in this window is not
displayed. You can use the PWREQ= data set option to control whether
a dialog box appears after a user enters a missing or incorrect password.
PWREQ= is most useful in SCL applications.
If you are using batch
or noninteractive mode, you receive an error message in the SAS log
if you try to access a password-protected member without specifying
the correct password.
If you are using interactive
line mode, you are also prompted for the password if you do not specify
the correct password. When you enter the password and press ENTER,
processing continues. If you cannot give the correct password, you
receive an error message in the SAS log.
