Oacres error - Lest than two stations

[Stefano Giorgetti]

I've created a station.map file with stnmap containing italian station
data, with this descriptor:
dset ^stRain.dat
dtype station
stnmap ^stRain.map
undef 999.9
title Accumulo pluvio dal 01/01/2005
tdef 1 linear 15:36Z19may2005 10mn
vars 1
rain 0 99 rain
endvars

Then I've created this dummy descriptor file

dset foo.dat
options template
undef -9.99e33
title dummy control file
xdef 360 linear 0 1
ydef 90 linear -90 1
zdef 1 linear 1 1
tdef 1 linear 0Z9jul2004 1dy
vars 1
dummy 0 99 dummy variable
endvars

I open dummy.ctl then stRain.ctl, but when I exectue the command
    d oacres(dummy, rain.2)
it returns the following error message:
    "Warning from OACRES:  Less than two stations
        Grid will be all missing values
    Cannot contour grid - all undefined values"

How can I solve it?

Thanks
