csh help

[John Townsend]

How, once I am in csh and am finished in the shell, do I get back to the
login shell.  I have looked through the man entries and can not find my
answer.

P.S.  I am looking for an effective screen lock program which will clear the
screen, and set up a nice _menu_like_ screen for entering lock key and 
unlock key.  I need it to work on the sun-4.
