The MASK command defines,
displays, and enables you to edit the contents of one or more new
lines that are created by the I command. The default setting for the
new lines are blank lines. To display or edit a new line, type MASK
in the number field of the line, and then press ENTER or RETURN. The
line with the contents defined by the MASK command is inserted. You
can then edit the line. A line with the contents defined by the MASK
command is inserted each time you issue the I command.
The contents defined
by the MASK command remain in effect for that window throughout your
current SAS session unless you change them. To change the contents,
type over the text. If you want to return to the default (a blank
line), do one of the following tasks:
-
blank any characters in the text
field of the MASK line.
-
issue the CLEAR command with MASK
as an argument:
clear mask
The contents of the
MASK line are cleared, and a note appears in the log indicating that
the MASK line has been cleared.
You can use the RESET
command or the D command to not display the contents of the MASK command.
The MASK command remains in effect even when it is not displayed.
For example, the MASK command remains in effect under the following
conditions:
-
when you scroll past the MASK line
and it is not displayed
-
when you issue the D or RESET command
without blanking any characters in the text of the MASK line
In some windows, such
as the
Program Editor window, you can use
the WSAVE command to permanently save the contents of the MASK command.
