[gradsusr] Plot first variable in ctl file when name is unknown

[Brian Gaze]

Thanks for that.

Using g2ctl (rather than alt_g2ctl) the variable names are predictable.
However when the grib2 file contains multiple elements the .ctl file gives
all the variables the same name (var000l150_150 in the example below).

The problem is I don't know how to reference the different variables in
GrADS. Any suggestions? The ctl is being generated from a DWD ICON grib2
file which should contain temperature forecasts at different atmospheric
levels (e.g. 850hPa).


dtype grib2
ydef 657 linear 29.500000 0.0625
xdef 1097 linear -23.5 0.062500
tdef 1 linear 06Z17jan2018 1mo
zdef 1 linear 1 1
vars 16
var000l150_150 0,150,45,46   0,0,0 ** reserved - reserved desc [unit]
var000l150_150 0,150,46,47   0,0,0 ** reserved - reserved desc [unit]

Thanks
