/*

A command consists of a primary keyword followed by one or more valid parameters.
A command ends with a semicolon (;).
Use a comma (,) to separate a primary keyword from a parameter. Also, use a comma between parameters. Do not use a comma after the last parameter in a command, before the ending semicolon.
In a SET_CONTROL_VALUE command, you can specify one or more global parameters. Global parameters are optional, but you must include at least one global parameter in the command. Alternatively, you can specify a separate SET_CONTROL_VALUE statement for each parameter.
In a registration-specific command, you can enter multiple parameters. Some parameters are required to identify the registrations to process, and other parameters are optional.
The utility parses and executes commands in the input stream one at a time from top to bottom.
You can repeat the SET_CONTROL_VALUE command in the input stream with different parameters or with the same parameters but different values for a subsequent set of registration-specific commands.
You can include parameters in a registration-specific command that overwrite corresponding global parameters in the preceding SET_CONTROL_VALUE statement. For example, include the REGISTRATION_LOCATION parameter in a registration-specific command to overwrite the GLOBAL_REGISTRATION_LOCATION parameter in the previous SET_CONTROL_VALUE command.
