It can be done directly using the vi editor, but JRMA
recommends copying the file to piptof1, edit with xemacs
(or whatever you usually use on linux)
and copying edited file back to deepthought.
MAKE A COPY FIRST (on deepthought) in case you bungle
something!! (cp fname1 fname2)
 

To copy a file to (and from) deepthought (from piptof1):
cd to the directory on piptof1 where the file you want to copy is, then

ftp deepthought
piptof
password
cd acqu/data   (or wherever)
put fname       (**** WARNING this will overwrite an existing file
                  with the same name, so CHECK what is there first!!)
quit
 
 

(Use get instead of put to copy fname in the other direction.)
 

If you don't know xemacs do

xemacs fname

to get it started - it has a help button. Basic stuff -Navigate with the
arrow keys, use the rubout key to remove a character and jst type in any
new ones.
Left click on file (top left) and on save (or save as to give a new file
name). Then left click on file and exit on exit to get out of xemacs. If
you changed something it will ask if you want to save it.
It is probably worth doing

more fname

to type the changed file to the screen so you can check the edit
really worked.

AVOID BLANK LINES at the end of files fro ACQU. They create total
mayhem!
