When specifying the default option for a command within a script or a macro, always specify the default value explicitly. Specifying command options explicitly helps clarify what the script or macro does if a problem arises, or if editing is needed.
If the defaults for a command change, having the options specified explicitly also removes the task of updating scripts or macros that use the command.
The command-specific HELP will state what assumed default values exist when the SET commands are used without specifying arguments.
