Specifies the dynamic name of a specific tool or application. For a list of valid subsystems, see Subsystem Types (see Subsystem Types).

Specifies the dynamic name of a parameter to be passed to the subsystem. This parameter is often a synonym for a command line flag or an object name.

The parameter can be any legal simple data type (integer, float, money, date, or varchar). Dates are stored as a varchar(25) and money is stored as the float data type.

Specifies the value to be assigned to the parameter. A value can be any simple variable expression that is understandable in the context of the parameter. Its data type must be compatible with the data type of the parameter to which it is assigned. If the value is a string literal, it must appear in single quotes.

To pass a parameter without an assigned value, use an empty string.
