[ferret_users] Re: ferret -script and arguments

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Patrick,
If you're running from the command line, you can put the list of names 
in quotes, and the whole string is treated as a single argument.

  yes? go myscript "file1.nc,file2.nc"

For the "ferret -script" mode, you're right, because the command parser  
looks for commas to separate the arguments that will be sent to the 
script, it sees only the first name as argument 1.  I don't see a way 
around that right now, but here is a workaround which I hope will be 
just as convenient.

If you put the list of files to open in a file, on a single line 
separated by commas, you can pass the name of that file to your script 
and have the script read the file names as a single string and use that 
string to open the files.

  > echo "file1.nc,file2.nc" > file_list.dat

Start the script myscript.jnl  with the commands

  SET DATA/FORM=delimited/VAR=all_files/TYPE=text/DELIM=" " ($01)
  DEFINE SYMBOL  file_names = `all_files`
  CANCEL DATA ($01)

  USE ($file_names)
  SHOW DATA

Then you can run this with

  > ferret -script myscript.jnl file_list.dat

and all the data files are opened.
