Can anyone tell me a little of the history of ex?  I would like to know
if it was developed simultaneously with vi (for use with the hard copy
terminals which were still common then) or if it preceded vi, and I would
also like to know if ed played any role in its development.  Are there
editing tasks which one can do in ed that one can't do in ex, or vice versa.
Is the regular expression code in ed also used in ex?

With thanks,
