In UNICOM Intelligence, the DSC's are often known by their short names, such as "mrSavDSC", "mrQvDSC", and so on. However, these names are not the proper COM class names that are required by the CreateObject function. For example to create the SPSS SAV MDSC object, the operation is CreateObject("mrSavDSC.SavMetadata").

You can use the DSC Explorer sample application to find out the class name string for a registered DSC.

An alternative way of creating the object is to use the DSC Registration component, as shown in the mrScriptBasic examples in 5: Creating Quancept script and mrScriptMetadata from an .mdd file.
