I set up a simple script to execute NCL's "system()" command to
create a zero-length file in my home directory.

cron is somewhat notorious for not necessarily executing in a user's
expected environment. By default, cron sets:

HOME=user's-home-directory
LOGNAME=user's-login-id
PATH=/usr/bin:/usr/sbin:.
SHELL=/bin/sh

If you want your .profile executed, you must explicitly do so in the
crontab entry or in a script called by that entry.

I essentially duplicated what you're doing, but made sure my script
had full pathnames specified for the NCL binary, and the file
containing NCL commands. Doing this did work.
