Glad this is working.

It's a function of the way the data is decoded.  For the ADDE data, the
value is converted to millibars when decoded, so that's how it gets
stored/displayed.  Since you can't physically convert units of millibars 
to inches of mercury we don't list that as an option.  There is an
empirical conversion, but you cannot do unit math to make the physical
conversion.  When we get the GEMPAK surface data reading done, you can use 
ALTI as a parameter and display it in inches (but not in millibars).
