UNIX on the VAX-11/750
                              ----------------------

The new UNIX system has some significant differences from the old one. Your best
course would be to look at (a) this document (b) the online documentation for
the commands 'man', 'more', 'apropos' and 'whatis' in that order. The list below
shows which commands are new or changed; a few new commands aren't mentioned,
either because they are too esoteric or because they are useless without extra
hardware (such as networking). A '+' in the left-hand column indicates that the
command is NEW.

The information below is the best that was available before the software 
is available on our VAX - so don't treat it as definitive. 

The control characters should be as before, viz. control-Z for end-of-file,
control-C to interrupt. The character for stopping a job (something which
didn't exist on the old UNIX) is control-X, not control-Z as the documentation
will tell you. The documentation about the whole system, when it arrives, will
actually be correct apart from the business of control-key functions - these
will be changed to what we are more accustomed to (i.e. as above).

NOTE that the commands 'lp', 'qs' and 'news' won't exist anymore under those
names - the corresponding new names will be 'lpr', 'lpq' and 'msgs'.

NOTE also that everyone will by default be using the new shell ('csh'), so
you will either have to change your shell files to work with it, or will
have to use the command 'chsh' to change the shell you use to the old one
(called 'sh' as before).
