SET DEFAULT PROTECTION Command
Function
The SET DEFAULT PROTECTION command sets a default protection code
for files you create during the job. Any value you set with this
command overrides the system's standard protection code. Your
system administrator sets the system's standard protection code,
which is usually <055> or <057>. The default protection code set
by using this command will be in effect for any of your programs.
Formats
SET DEFAULT PROTECTION <nnn>
SET DEFAULT PROTECTION ON
SET DEFAULT PROTECTION OFF
Where: <nnn> is the value that you can specify as the
protection code for any files you might create.
ON tells the system to use the protection code you
specified previously, even though you may have since
used the SET DEFAULT PROTECTION OFF command.
OFF tells the system to use the system's standard
protection code when you create files, even if you have
issued a SET DEFAULT PROTECTION <nnn> command.
