The OBJECT GET MINIMUM VALUE command returns, in the minValue variable, the current minimum value of the object(s) designated by the object and * parameters.
You can set the "Minimum Value" property using the Property List in Design mode, or using the OBJECT SET MINIMUM VALUE command.
Passing the optional * parameter indicates that the object parameter is an object name (string). If you do not pass this parameter, it indicates that the object parameter is a field or variable. In this case, you pass a field or variable reference instead of a string (field or variable object only).
