[ncl-talk] write netcdf

[Toni Klemm]

Hi Debasish,

Try taking out the space between systemfunc and (“date”) here:

> fAtt at creation_date = systemfunc ("date")


which changes it to this:

> fAtt at creation_date = systemfunc("date")


If that doesn’t solve it, try taking the spaces out of:

>  fileattdef( fout, fAtt )


to this

>  fileattdef(fout,fAtt )



Good luck,
Toni
