A new version to C-swing is being relased.
The Patches to uppgrade from 3.6.2 to 3.6.3 will be posted to
vmsnet.sources.

If you like to have the new version it's on anonymous ftp
at rigel.efd.lth.se (130.235.52.10)

This information is from the readme file.

C Swing is a file and directory management utility.

New in v3.6.3:  All of the following changes for v3.6.3 are from
	Foteos Macrides, who has done a great deal of work.  Thanks!

    	o Fixed more bugs in code for searching for directories under a
	  000000 directory if the device__000000_SWSVE.DAT file exists
	  and the device__directory__SWSVE.DAT file doesn't.  Made this
	  behavior an option via a -0 or /0 qualifier.  It can be made
	  the default (i.e., regardless of whether -0 or /0 is entered on
	  the command line) by defining ALWAYS_TRY_000000 in SWING.H.
	o Enhanced or debugged aspects of logical device name handling.
	  However, earlier modifications to respect terminal and concealed
	  device logicals have broken some of CSWING's capacity to deal with
	  search lists, and it can't all be restored without a major rewrite.
	o Added code such that arguments or logicals which translate to
	  SYS$SYSROOT:[directory] will cause SYS$SPECIFIC:[directory] and
	  SYS$COMMON:[directory] trees to be displayed (SYS$SPECIFIC is not
	  in the SYS$SYSROOT search list, so it must be treated as a special
	  case).  Optional defines (SPECIFIC_EXITS_TO_SYSROOT and
	  COMMON_EXITS_TO_SYSROOT) in SWING.H enable setting the default
	  device to SYS$SYSROOT on exit in SYS$SPECIFIC or SYS$COMMON if an
	  original call was for SYS$SYSROOT.  Added a -s or /s and a -c or
	  /c qualifier to evoke this behavior if SPECIFIC_EXITS_TO_SYSROOT
	  and COMMON_EXITS_TO_SYSROOT, respectively, are not defined in
	  SWING.H.  For all other search lists that can be handled, the
	  default directory on exit is always that of the particular tree
	  you were in at the time of exit.
	o Modified the command line (-h) help module to describe the -0, -s
	  and -c qualifiers if they were not made defaults via logicals in
	  SWING.H or by including them in the foreign command definition
	  for CSWING.
    	o Added capacity to handle relative directory specs (e.g., [.foo] or
	  [-.-.foo]).  An argument with such a spec is handled relative to
	  the directory from which CSWING was called, regardless of its
	  position in an argument list (e.g., the list  SYS$MANAGER,[]  will
	  put up trees for SYS$SPECIFIC:[SYSMGR], SYS$COMMON:[SYSMGR], and
	  your calling default, in that order).
	o Added pause and prompt features for displays of CSWING.HLB (like
	  those when reading help libraries via DCL).  The help page length
	  is determined by the value of page_length, determined at startup
	  of CSWING.
        o Modified swing_8.c and swing_38.c to enable calling MOST with a
	  set of selected files, and thereby use MOST's windowing features
	  for multiple files (and appropriately modified the quick help list
	  in swing_22.c).  Made numerous modifications/enhancements of MOST
	  for maximum compatibility with CSWING, as described in the header of
	  MOST's main.c.  Most noteably, command keys are now the same as or 
	  homologous to those of CSWING wherever possible.  MOST called from
	  CSWING will read and use MOST_SWITCHES and MOST_EDITOR if defined,
	  can spawn editors and will use that defined for CSWING if its own
	  logical is not defined, and can spawn to DCL in a manner analogous
	  to spawns from CSWING (or will respect the 'captive' restriction if
	  set).  Also modified main.c so that a standalone MOST can be built
	  with the same code at that for CSWING.  Added confirmation of intent
	  to edit in swing_16.c and MOST (our users too often hit E with
	  intent to exit, not edit).  Provided a MOST.DOC_FM for this version
	  of MOST (Note that the original copyright applies to it, and to any
	  programs derived from it:  You must freely distribute the source
	  code.).

There is also a new DCL_SWING.HLP file from Greg Orman which you may wish
to include in the system-wide help library (SYS$HELP:HELPLIB.HLB).

For those not familiar with C Swing, here's an excerpt from the readme file:

SWING is a VAX/VMS utility for displaying the graphic  representation  of  the
VMS  directory  structure  on any terminal that can support the SMG routines -
that is primarily the VT100, VT200 and VT300 series  of  terminals.  SWING  is
designed  to  make  life  easy for a user who frequently performs directory or
file operations within his or her directories.

SWING displays  the  top  eight  directory  levels  of  the  user's  directory
structure.  If  there are more than eight levels a diamond is displayed in the
right-most column indicating that there are non-displayed directories.

SWING has a two level help facility. Quick  menus  are  available  via  the  ?
option. Standard VMS help is available via the H or HELP (LK201) option.

The C language version of SWING was written by Simon Brown, and maintained  by
him  through  V3.2.  It  has  been  modified  by many people, and is currently
maintained primarily by Mats Akerberg and Harry Flowers  (see  end  of  file).
Most  of  the  documentation  has  been rewitten by Chris Butler. Although the
online help is good, you should read the manual. The re-write was necessary as
he  did  not  have  a Fortran compiler, and felt that C was a more appropriate
language. Also, colleagues required major enhancements, so  the  software  was
started  from  scratch. The result that you see here consumed something in the
region of 400 to 500 hours of spare time. The software has been placed back in
the public domain.

As always, we're interested in any bug reports/enhancement requests that you
might have (not that we promise to fix/implement them ;-), but chances are
much better if we know about them).
