[ncl-talk] segmentation default when reading variables

[Rick Brownrigg]

Hi,

Are you able you able to ftp the file in question to us?  Using "addfile()"
with "w" to both read and write should work, and in any case, it should not
segv!

ftp ftp.cgd.ucar.edu
anonymous*<enter your email address for the password>*
cd incoming
put *file1*
put *file2*
. . .*continue with 'put' commands until all desired files are uploaded*. . .
quit

When the upload is complete, send email to ncl-talk <ncl-talk at ucar.edu> or
the NCL team member that you've already been working with and include the
exact names of the files, and the approximate size of each file.

For security reasons, you cannot list the contents of the 'incoming'
directory. This is why we need to know the exact names of the files.
