You could create a Jython procedure like:

def scaleAndOffset(field, sc, off):
    offset = float(off)
    scale = float(sc)
    return scale*field + offset

and then create a formula:

scaleAndOffset(field, scale[isuser=true,default=1], 
offset[isuser=true,default=0])

which will prompt you for the scale and offset values.

However, you might get what you want by changing the units as I described
earlier.
    

b[isuers=true] + c*a[isuser=true]

where you will be prompted for b and a as numbers
> And last, is there a training session planned at Unidata Center ?

Our next planned session is for Summer 2009, but that may slip to
fall because there is a political convention in Denver then and hotels
are all booked.
