right. environment variables are inherited (copied on creation) by
child processes. your interactive shell is parent to the new instance
of tcsh running your script, but the parent does not see the settings
made within the script.

yup.

right again. the "source" command causes the statements in the
specified file to be executed by the current shell instance, not a new
instance.
