Re: Converting 6-hour Data to Daily Averages

[Jonathan Callahan <callahan@xxxxxxxxxxxxx>]

Jeremy,

I can't tell from your email whether you are using forward tics or back tics (grave accents).   Check out the
Users' Guide section on "embedded expressions":

http://ferret.wrc.noaa.gov/Ferret/Documentation/Users_Guide/v44/chapter3.html#expression$embedded

When using back tics, "Ferret will replace the full grave accent expression, including the accent marks, with
an ASCII string representing the numerical value."  This does work in your example.
