* Control Parameters are set by the user to control the software; Info parameters are informational output parameters.

** Note that for parameters whose type is 'pointer', you can set the parameter without making it a pointer first - the object will take care of that.  And when you retrieve a parameter that is a pointer, unless you use the /NO_DEREFERENCE keyword on the call to GET, the contents of the pointer will be returned, not the pointer.

*** User Levels are:
   Standard - parameters that most users will want to set
   Advanced - parameters that require a high level of familiarity with the software
   Expert - parameters that should never be set by users
