Hi Ghetiya,
Yes, I wan to read all the files in through the repeat loop. When you say nested loop, do you mean let datset=0; repeat/range=1:8 (let datset=`datset+1`; use `files_CNRM[X=datset]`)? It didn't work. The error message is like **ERROR: command syntax: DATSET // SET DAT/FORM=CDF `files_CNRM[X=datset]`. I feel datset needs a pair of grave accent to make it as an variable. However, ferret considers the nearest two grave accents as a pair. I might need to read my files in one by one instead of using repeat loop.
Thank you very much and have a nice day.
