Re: Memory leak with array overwriting

Hello,

Can you please provide us with a small sample script
that illustrates the problem? Also, a sample data file?

Please ftp to

ftp ftp.cgd.ucar.edu
anonymous
Use your email address for the password
cd incoming
put your_ncl_script
put your_data_file(s)

quit

Send us an email with the following information:

* The names of the files after you have successfully completed the
transfer. We cannot look at the ftp/incoming directory for security
reasons.

THX
