How to determine if controller is single or dual channel

I need for my Microbasic script to know if it's running on a single or dual channel controller.  The only command I've seen that provides this information is the TRN query, but it returns a string and there are no string variables in Microbasic.  The manual says you can execute getvalue(_TRN,1), and even says the reply is a string which I can't use.  I tried the T query, but even the manual states that some dual channel models only have 1 heatsink temperature, so that won't work.
