String substitution commands are initiated by first giving a normal FIND
command   but  using   the  special   string  terminating   character  \
(back-slash),  typed  with  both  the  <META>  and  the  <CONTROL>  keys
depressed. This  is then  followed by the  substitution string  which in
turn  is terminated  by either  a simple  carriage return (which  may be
preceeded by an argument, typed with control keys) or by <CONTROL><CR>. 
Note, many of the otherwise acceptable Find command terminations are not
meaningful with the substitution commands and are not allowed.

Sample commands.

   αβFSTRINGαβ\"String"αβ∞<CR>	Find all occurances of the string
                STRING,  whether typed  in  lower or  upper  case
                letters  and  replace  them  by the  substitution
                string as typed, that is, enclosed in  quotes and
                with the initial letter only  in CAPS.  Limit the
                search  to the current page starting at th cursor
                location. 

   αXFIND ←αβ\ <BACK ARROW> α<CR>	 Find the first occurance
                of the character  ←  whether on the  current page
                or a subsquent one and  replace it  by the string
                <BACK ARROW>  (including  the <  and >) and  with
                spaces   introduced   before  and   after   these
                characters.    Leave  the resulting  line  in the
                Line-Editor. 

The <CR> termination is the faster mode of operation in  that it makes a
minimum use  of the line editor  and it is recommended.   This mode does
have one defect in that the substitution is completed and is not subject
to the simple <ALT>  method of aborting a single line  correction.  When
the <CONTROL><CR>  termination is used the substitution  is made via the
Line-Editor and the results are left in the Line-Editor's buffer so that
the substitution may  still be aborted by the usual  <ALT> command. This
takes time and certain timing difficulties sometimes cause trouble. 

The usual  rules apply to the specification of the searched-for string. 
The substitution string may, however, contain certain delimiters (spaces
in particular) whether or not the search is for a delimited string and a
distinction is  made between  upper  and lower  case letters.  Only  the
searched-for letters without delimiters are replaced. To be specific, if
one  were to replace a  delimited string by a  null substitution string,
the two delimiters would remain in the corrected text. 

The substitution string is sticky, so that a substitution  command, when
successfully executed  for a single  occurance, may be repeated  for the
next  occurence by typing αβ\ only.  The typing of  a new string for the
searched-for  string  destroys  the  record  of   the  previously  saved
substitution string  and the entire request must  be retyped before this
command will be honored. 

A null substitution string may be  used but only after confirmation  has
been requested and received. The substitution will also be restricted to
a single occurance.  It may then be repeated as many times as desired by
the usual repeat command with the desired argument.    These precautions 
can be removed if users find them bothersome, but it was thought wise to
put them in at first.

Multi-page substitutions  are useful  but potentially  dangerous as  the
substitutions made on  any one page are, of course, written out onto the
disk file when ever a new page is entered. 

As noted earlier, typing αβ\ after a successful single substitution will
repeat the  substitution. This command  may be preceeded by  an argument
(with control  bits) and the substitution will be repeated the specified
number of times.  Should substitutions occur on more  than one page, all
substitutions on pages earlier than the last page will have been written
out. 

The use of the  command α\ rather  than αβ\ is also  allowed but is  not
recommended. This leaves  the altered line  in the line buffer  with the
possibility of an <ALT> abort. 

Sample repeat commands.

   αβ\		Repeat  the previously made substitution  at the next
                occurance of the searched-for string using the faster
                and  safer mode which  does not leave  the results in
                the Line-Editor buffer. 

   αβ6αβ\	Repeat the substitution for the next 6 occurances.

   α\		Repeat the substitution once but leave the results in
		the Line-Editor buffer.

1 MARK PAGE 3 PAGE MOVING commands. 


 You are  now looking at a longer  page than before. Note two  things: 1
The top line contains asterisks, the page number and the file name.  2 A
bottom line contains dashes, where  formerly there were asterisks.   The
asterisks mean that you are seeing the page through a window starting at
the top of the page, while the dashes mean that there is yet more on the
page than that  shown.  On moving  the window down, dashes  will replace
the top asterisks.  If you can then see to the end of the page asterisks
will appear at the bottom. 
aaaa
 Note also that there are some  lines at the very bottom that echo  your
command or  acknowledge  its execution.   Watch  these  lines to  detect
errors. 

 Several  commands allow you to move the window  up and down on the page
and to move the CURRENT line marker (the arrow on the left) around.

A practice line to TEST the problem of a period at the end of a line.
A  1practice line to  TEST the problem  of a period  at the  end of a
line.  A 12practice line to  TEST the problem of a period at  the end
of a line.  A 123practice line to TEST the problem of a period at the
end of a line.  

It is good practice to limit the page si*e to less than 150 lines.  This
eases the load on the editor and makes the directory of more use, if you
adopt the practice  of starting each  page with a  suitable comment.   E
keeps certain vital statistics packed into 9-bit  bytes and it gets into
trouble if there are more than 511 lines on any one page. 

 Note  that the window moved down on the page  only far enough to get to
the end of the page.  Had the page been longer, an entirely  new window-
ful might have appeared (except for the former last line which now would
become the first line). 

  The → which  had previously been  attached to the first  line of text,
moved to the  last line and stayed  with it as  the window moved.   This
arrow points to  a line called CURRENT.  This  line would be affected if
you were to do some line editing. More on this later.
