This command sets and prints the default printing depth. If depth is not given, this command prints the default printing depth. If depth is given, it must be a positive integer and is used to reset the default printing depth.
The "default-print-depth" parameter is used to control the default printing depth of the print command. The default initial setting of the "default-print-depth" parameter is 1.
This parameter can be overridden in any invocation of the print command by using the -depth option.
