Doing a Custom Inventory based on the Command script option.

I've got a custom data class and I need to run a Command Script to get the results.  I'm running a very complicated Dsget command that is returning only a single value and is becoming almost impossible to run within a VBS. 

Can anyone tell me how to kick off a custom inventory using the Command Script that returns a single value and kicks off the inventory process so it creates the NSE file?

There does not seem to be any examples on connect for this process.  I've looked at HOWTO50026 and various other connected to this howto and yet cant find any that involve command script. 

Help.
