clhilo

[Javier G. Corripio]

Hi there,

Is anybody using clhilo successfully on the last version of Grads (v2.0.a3), to plot H and L on
pressure charts?

I don't have a f77 compiler, so I did it with f95, it seems ok
created /usr/local/grads/udft
export GAUDFT="/usr/local/grads/udft"

with:
ls /usr/local/grads/udft
clhilo.exe  udft.clhilo

and cat udft.clhilo
clhilo 1 5 expr value value value char
sequential
/usr/local/grads/udft/clhilo.exe
udf.clhilo.gfi
udf.clhilo.gfo


HOWEVER

When using the example provided I always get this error

Config: v2.0.a3 little-endian readline printim grib2 netcdf hdf4-sds
Issue 'q config' command for more information.

any suggestions?

What is the qqqqqqqqqqqq 100 500 ??

Thanks a million,
