Does anyone have a working example of using the NextAnalysisStep method to
Design Storage in either JScript or VBScript ?

The example in BOL does not work. Specifically, using:

dsoPartitionAnalyzer.NextAnalysisStep(dPercent, dSize, lAggs)
never assigns values to the 3 parameters.

I would settle for a solution in a DTS package. Is a Visual Basic program
the only way to programmatically design storage ?
