1 CHANGE_HIDE
 CHANGE HIDE

  Used in conjunction with FIND ALL and WILDCARD FIND ALL, changes between
  having EVE hide all lines in  the  buffer that do not contain the search
  string  or pattern, and displaying all lines regardless of whether  they
  contain the search string or pattern.

  If previous to using CHANGE HIDE, EVE was set to hide lines in a buffer,
  following the command,  EVE  will  display  all  lines  in the buffer on
  subsequent FIND ALL or WILDCARD FIND ALL commands.

  If previous to using CHANGE HIDE, EVE was  set to display all lines in a
  buffer  following a FIND ALL or WILDCARD FIND ALL command, regardless of
  whether they contain the search string or  pattern  (nohide),  following
  this  command,  EVE  will  hide all lines that do not contain the search
  string or buffer.

  If FIND ALL or WILDCARD FIND  ALL  is  active in the current buffer, the
  CHANGE  HIDE command acts immediately to change the display of lines  in
  the current buffer.

1 FIND_ALL
 FIND ALL

  Searches for a string of  text  you  specify, highlights all occurrences
  of the found text, and displays all lines containing the text.

  Lines not containing the  found  text  are  hidden from view, unless the
  user has issued the SET FIND ALL NOHIDE command.

  Steps:

     1.  Use FIND ALL (either press the key FIND ALL is mapped to,
         or use <DO> and type FIND ALL at the prompt).

     2.  Type the text you want to find (see examples under the
         FIND topic) and hit <RETURN>.

     3.  To re-display all lines in the buffer, use the RESET command
         (usually GOLD/SELECT), or use FIND ALL in the buffer, but hit
         <RETURN> without typing any text.

  Usage notes:

  o  The conventions used for  matching  or  ignoring  the case of the
     search  string are identical to those used by FIND.  Refer to the
     FIND HELP topic for details.

  o  If the SET FIND ALL  NOHIDE  command  has been given, the matched
     strings  are  highlighted, but all other lines in the buffer  are
     still displayed.  In this  case,  the  restrictions  and  changed
     behaviour  listed  in the items below do not apply.  SET FIND ALL
     HIDE restores the default of displaying only those lines in which
     the string was found.

  o  While displaying only lines in which the search string was found,
     the hidden  text  is  made  unmodifiable  to  prevent  unintended
     changes.  You may continue to modify the displayed text.

  o  While displaying only lines in which the search string was found,
     FIND, FIND NEXT, FIND SELECTED, WILDCARD FIND, and REPLACE may be
     used and will match only to  strings  that are found in the lines
     being  displayed,  not  to strings found in hidden lines  of  the
     buffer.

  o  While displaying only lines in which the search string was found,
     use of SELECT, REMOVE, INSERT HERE,  and COPY (STORE TEXT) should
     be  AVOIDED.   SELECT/REMOVE will usually be converted to a  COPY
     operation, and the text copied to the  INSERT  HERE  buffer  will
     include  hidden  lines.   INSERT  HERE  operations  will _not_ be
     prevented and all text inserted will  be visible.  Thus a SELECT/
     REMOVE/INSERT  HERE sequence will result in a _duplicate_ of  the
     selected text being inserted into the buffer.

  o  Use of ERASE LINE  followed  by  RESTORE  LINE  should be AVOIDED
     since  the  restored  text will usually NOT be  replaced  at  its
     original location in the buffer.

1 SET_FIND_ALL_HIDE
 SET FIND ALL HIDE

  When using the FIND ALL or WILDCARD  FIND ALL commands, instructs EVE to
  hide  all  lines that don't contain the search string or pattern.   Only
  those lines containing the search string or pattern are displayed.  This
  is the default.

  Usage Notes:

  o  If when the SET FIND ALL  HIDE  command is used, FIND ALL was set
     to  display  all lines in the buffer (nohide), and if the  ranges
     found in the current buffer by  [WILDCARD]  FIND  ALL  are  still
     being  highlighted,  then  SET  FIND ALL HIDE will hide all lines
     that do not contain the search string or pattern.  Other buffers,
     which may also be displaying the results of a [WILDCARD] FIND ALL
     command, will not be affected.

1 SET_FIND_ALL_NOHIDE
 SET FIND ALL NOHIDE

  When using the FIND ALL or WILDCARD  FIND ALL commands, instructs EVE to
  continue displaying all lines of the buffer, whether or not they contain
  the search string or pattern.  All matches found will be highlighted.

  Usage Notes:

  o  If when the SET FIND ALL NOHIDE command is used, FIND ALL was set
     to hide lines in a buffer which do not contain a found range, and
     if there are lines in the current  buffer still being hidden as a
     result  of  [WILDCARD]  FIND ALL, then SET FIND ALL  NOHIDE  will
     re-display all the lines in the current buffer.   Other  buffers,
     which  may  also  be  hiding  lines  due to a [WILDCARD] FIND ALL
     command, will not be affected.

1 WILDCARD_FIND_ALL
 WILDCARD FIND ALL

  Searches for a pattern  of  text  by  using  wildcards (sometimes called
  "meta-characters"),  highlights  all occurrences of the found  patterns,
  and displays all lines containing the text.

  Lines not containing the found pattern  are hidden from view, unless the
  user has issued the SET FIND ALL NOHIDE command.

  Steps:

     1.  Use WILDCARD FIND ALL (either press the key the command is
         mapped to, or use <DO> and type WILDCARD FIND ALL at the
         prompt).

     2.  Type the pattern you want to find (see examples under the
         FIND topic) and hit <RETURN>.

     3.  To re-display all lines in the buffer, use the RESET command
         (usually GOLD/SELECT), or use WILDCARD FIND ALL in the buffer,
         but hit <RETURN> without typing a pattern to find.

  Usage notes:

  o  The syntax used to specify a pattern using wildcards is identical
     to that used by WILDCARD  FIND.   See the examples listed in that
     HELP topic for details.

  o  If the SET FIND ALL  NOHIDE  command  has been given, the matched
     patterns  are highlighted, but all other lines in the buffer  are
     still displayed.  In this  case,  the  restrictions  and  changed
     behaviour  listed  in the items below do not apply.  SET FIND ALL
     HIDE restores the default of displaying only those lines in which
     the pattern was found.

  o  While displaying only lines in  which  the pattern was found, the
     hidden  text is made unmodifiable to prevent unintended  changes.
     You may continue to modify the displayed text.

  o  While displaying only lines in which the pattern was found, FIND,
     FIND NEXT, FIND SELECTED, WILDCARD FIND,  and REPLACE may be used
     and  will match only to strings that are found in the lines being
     displayed, not to strings found in hidden lines of the buffer.

  o  While displaying only lines in  which  the pattern was found, use
     of  SELECT, REMOVE, INSERT HERE, and COPY (STORE TEXT) should  be
     AVOIDED.  SELECT/REMOVE will  usually  be  converted  to  a  COPY
     operation,  and  the  text  copied to the INSERT HERE buffer will
     include hidden  lines.   INSERT  HERE  operations  will  _not_ be
     prevented  and all text inserted will be visible.  Thus a SELECT/
     REMOVE/INSERT HERE sequence will result in a _duplicate_  of  the
     selected text being inserted into the buffer.

  o  Use of ERASE LINE  followed  by  RESTORE  LINE  should be AVOIDED
     since  the  restored  text will usually NOT be  replaced  at  its
     original location in the buffer.
