Command parameters

Positional parameters must be placed in a certain position within a command. Keyword parameters are assigned a value and can be placed in any order within a command. The first keyword parameter used in a command must be preceded by a left parenthesis.

If a command allows keyword parameters, you can use as many as you need. If you use a keyword parameter more than once in a command and provide different values for the parameter, its last value takes effect. No parameter value can be longer than 80 characters.

All parameters are separated from each other with a blank or a comma followed by an optional blank. For example, all of the following specifications are correct:

A right parenthesis is not required, but can be used to end the command. Anything you put after it is treated as a comment; it is not processed.
