Thanks for the tip (I got another offline about this command -- thanks).
Never thought of using context help with reload. I can see where this would
be really helpful to save yourself in scenarios like you mentioned. Out of
curiosity, what kind of statements can you put as 'LINE' to trigger a
reload? Is there a way that I could have it reload in X minutes if E0 gets
shutdown, for example (to save me from myself)? Just wondering... Good
feature either way.
Thanks,
-Jeff
