		Release notes-outer 3.4   (Aug 10)

	outer 3.4 fixes a bug introduced in outer 3.0.  This bug
produces incorrectly levelized data in some cases where levels are entirely
"projected out" of the object.  The bug most frequently manifested itself
during plotting, where the plotting software asked for just the
object level containing the x & y variables.  The plotting problem 
manifested itself as "only the first part of the data plots"

	outer 3.3 puts more information in the "Plotting and Other
Operations" link.

==================== [repeat of outer 3.2 changes]

	outer 3.2 contains a fundamental change in handling
selection/projection lists where selection variables are not in
the projection list.  The new behavior is documented in the file
selection_vars_not_projected.doc, included in this release.
	This change made the use of the logical "not" operator
more reliable.  The "Plotting and Other Options" server will
be modified to offer a "not" selection.  To enable this feature,
define the variable $option_server_program in jgofsroot/build-env.pl 
to "jg/otheropt3"

	The selection parsing routines used by outer (previously
in the outer distribution; now in the libupd distribution) originally
required a function called iovalreal_.  Later (~1998) a choice was
added.  By default, iovalreal_ was used.  However, if compilation
switch USE_DOUBLE was specified as TRUE, a function called
iovaldouble_ was used instead.
	In outer 3.2, only iovaldouble_ is accepted, and the
USE_DOUBLE compilation switch is obsolete.  This modification
requires modification to the make files that include outer as
part of their build.
    1) If USE_DOUBLE was not specified, or specified as
	USE_DOUBLE=0, an iovaldouble_ function must be
	added.  The libupd package includes iovaldouble_stub.o
	which can be added to the appropriate make file.  It
	calls iovalreal_.
    2) If USE_DOUBLE was specified any other way, then the
	iovaldouble_ function is already available.  The make
	should succeed.
    3) If USE_DOUBLE is specified at all, a diagnostic will
	be issued informing the user that the switch is
	obsolete.  Removing the specification will remove
	the diagnostic.

	outer 3.2 changes the way ".flatN" output handles
the display of variable attributes.  ".flatN" output is most
frequently produced by the use of the "Flat Listing" button in
an html display of the data.  
	There are 2 new switches; FLAT_WIDTH_ATTR and 
FLAT_NONWIDTH_ATTRS.  They control the display of the 
"width=" and all other attributes, respectively.  The
defaults are FLAT_WIDTH_ATTR=FALSE and 
FLAT_NONWIDTH_ATTRS=TRUE.  Please see outer_switches.doc
for details about setting switches.
	Previous versions of outer displayed attributes
unless one of them was width=.  Since one of them
was ALWAYS width=, attributes were never displayed.
This code seems to have been an error.

===========================================

		Files

	This tar file is generally used by unpacking its contents
in the directory jgofsroot/src/methods, followed by rebuilding those
methods that use outer.  See jgofsroot/build.doc for a description of
the "standard" system build procedure.  Local modifications will presumably
be described locally.

		Documentation

	The comments at the top of outer.c are the most complete
documentation of the changes in this release.  Other .doc files
included in the release (in decreasing order of expected general usefulness):

outer_switches.doc
	Summarizes available compilation switches.  
	Most compilation options are also available as 
	environment variables at runtime.

brev.doc
	A discussion of the ".brev" data listing feature.  

selection_vars_not_projected.doc
	Describes outer's behavior when variables in a selection are 
	not desired in outer's output

outer_revision.doc
	Contains older source comments removed, for convenience, from outer.c

method_arguments.doc
	A discussion of a proposed syntax to allow inners to receive 
	non-positionally-determined arguments (as well as a description 
	of the problem being addressed).
	Primarily for programmers writing inners.
