The trouble with copying files is that you can not use both terminals--
maybe not a problem for you. In SunOS, vi checks for the environment
variable EXINIT, so you could do the following:

if ("$term" == "op4x) setenv EXINIT ":so ~/.exrc.op4x"
if ("$term" == "sun") setenv EXINIT ":so ~/.exrc.sun"

($term == $TERM in SunOS csh)

Contrary to the 'man vi' ~/.exrc cannot exist if you want to use the
EXINIT environment variable.

If you have generic stuff to use for both terms, add ':so ~/.exrc.gen'
to the bottom of each of the above init files and put the generic stuff
in ~/.exrc.gen
