Re: fatal:syntax error: line -1 before or near .

This reminds me of a quirk I have seen occasionally when using a
shell script as a driver for an NCL script. NCL may continue
reading from "standard in" past the end of the script, and start
processing an input stream that belongs to the shell script, as if
that stream was additional NCL statements.

The workaround is to simply add an "exit" statement as the very last
physical line of the NCL script. This forces NCL to terminate at
the proper time.

I do not know whether this quirk is active in the current version of
NCL. HTH.

>>> I apologize for this posting being so long but I believe that I must inform you on what this code is actually doing before trying to debug. I am currently running the single column WRF model for ensembles. The WRF is an idealized version needing only input sounding and soil profiles. I have written an NCL script that interpolates the 90 m wind speed and writes is to a file named 'test.txt'. In order to do all of the ensembles I have written a shell script that reads the sounding time and date from another directory and injests it into the WRF. Then it calls the NCL script to write the wind speed to a file to be concatenated together at the end of the ensemble run. This all seems to make logical sense but unfortunately I keep getting an error from the NCL script. The error is:
