		DIFFERENCES BETWEEN "E" AND "TV"

	This  document is  intended  to help  TV  users get  started
using  E. The  reader is assumed 		MISCELLANEOUS FEATURES (cont)

	E allows read-only  editing of unformatted  files.  If  /R is
specified and the file  is not in E/TV format,  it will edit the file
without requiring conversion.  The ⊗XREADWrite command is  illegal in
this mode.  Naturally,  the  speed advantage of random access is lost
to some  extent,  but a directory is incrementally created in core as
each page  boundary is  encountered during  the edit.   The  current,
possibly  incomplete,   directory  can be  examined  as page  0.   An
attempt to go to a page beyond the known locations will read in  each
page from the  last one known to the  desired one in order  to locate
it.  Positioning   up  to  and  including  the   page  one  past  the
highest-numbered page referenced during  the edit can always be  done
by random-access. 

	E provides text justification similar  to the SOS JU command.
The  command is ⊗XJUst. Normally (when not  in attach mode),  it will
justify the whole current page  if no argument is given,  or  N lines
beginning at the  current line where N is the  argument.  In order to
make range specification easier,   the default range while in  attach
mode  is  the  contents  of the  attach  buffer.    This  way,    the
appropriate  range can be determined  experimentally by attaching the
right number  of lines and  then doing  a ⊗XJU.   If  an argument  is
supplied, the first  N lines of the attach buffer  will be justified.
The  parameters LMAR,   PMAR, and  RMAR cannot yet  be set,   but the
defaults are the same as SOS  (1,  1,  69).  Equivalents to  JL,  JR,
and JC do not exist.   There is an additional command ⊗XJFill,  which
breaks up lines as in JU, but does not insert any extra spaces.

	Occasionally  it  is  necessary  to  use  outmoded  low-speed
terminals (such as those kludges referred to  as "teletypes").  While
SOS is  probably a better editor to use  under such circumstances,  E
does attempt to be operable.   No provision for control bit input  is
made,   but  since  characters lose  their line-editor  significance,
most  commands can  be typed  without them.   A notable  exception is
αβ<cr>,    for which  the  equivalent  (and  more  mnemonic)  αβI  is
provided.  The "display" consists  of typing the current line when it
changes preceded by its sequential line number within the page,   and
preceding that by  the page when  it changes.  No  intra-line editing
is available,   and Stanford AI special  characters can only be typed
as their corresponding "control" characters.
