Yes to both!

I see! So in summary  blah_mode_hook()s are used _only_ when
blah_mode.sl needs to be customised. So what is the syntax for writing
a xxxxx_mode_hook()?

html-mode now appears to be working automatically. I'm using Jed on an
OS X Leopard box, so maybe some of the Terminal setting were a bit
off. I fiddled with the settings and I now have one-color syntax
highlighting - red - for the html tags. Not great, but better than
nothing.

I will soon be interested in writing a "mode" for a language that I'm
learning - Mumps (or M Technology as it's currently called). If I take
an existing .sl mode-type file in JED_ROOT and modify it, that could
be a good start? Then I can call it up automatically in my .jedrc file
using () = evalfile("mumps.sl")? or from jed using S-lang () = blah
blah. How would I set up the M-x mumps-mode thing? TIA....
