Hi Peter, Yes, this looks like a bit of a bug. It also occurs in earlier versions of Ferret, so has been in the code all along. It looks like it comes from the option to SET LIST/FILE=AUTO orwhich generates a filename from the input dataset and variable name. When Ferret parses command lines, options are generally just compared up to the first four characters; but here it might be a good idea to see if there's more after the letters "AUTO". You would not run into this if you used, say, Thank you for the report and the example.list/noheader/file=tautocor_nino_INDO.dat/ Ansley Seon Tae Kim wrote: I am using Ferret V6.3 on a linux machine. I tried to save a variable using the commend "list" like use wp_anomaly_INDO.nc let r_nino = tauto_cor(nino34) list//noheader/file=autocor_nino_INDO.dat/format=(f13.5) r_nino After that I have a message, !-> list/noheader/file=autocor_nino_INDO.dat/format=(f13.5) r_nino LISTing to file Wwp_anomaly_INDOR_NI.Z0T05673 So I had a file Wwp_anomaly_INDOR_NI.Z0T05673 instead of autocor_nino_INDO.dat If I remove "auto" in the file name like autcor_nino_INDO.dat, the variable is listed in the autcor_nino_INDO.dat Therefore, in Ferret 6.3, we do not use a file name with "AUTO". Is it a bug of version 6.3 ? -Peter |
