Hugh: MY experience is that editing directly on the CRAY is
VERY frustrating  (UNICOS).  I have to log in via phonelines
or networks and the delays both with UNICOS swapping and network
make working with VI (say) almost impossible.  Having to wait
a few seconds for responses leads to real confusion.  And
editing mistakes.  For small editing situations (changing a few
syntax errors for example) its alright.  But any extensive
restructuring of a program I'd rather edit it on my workstation
and use KERMIT to upload to the Cray.  The problem is trying to
do critical work (like editing) in a timesharing environment.
What I have done is build a small testbed in my Apollo so I 
can develop codes locally and only later bring them to the
Cray.  But then again, my Cray isn't in the next room.
(Its 3Kmiles away).
