Re: using environment variables in NCL script: arrays

Cathy,

In Perl, create a single long string containing numbers separated by
spaces, e.g. "100 200 300". Assign this long string value to the
environment variable. Other delimiters are possible, if space is not
available for some reason.

Then in NCL:
levels = toint (str_split (getenv ("levels", " ")))

--Dave
