This is a good goal. Sometimes, however, upgrading requires one to
make changes to the application.

Okay.

ActiveTcl is what the community calls a "Batteries Included" distribution.
That is to say, it includes the base language, Tcl, along with a number
of commonly used add-in functions/modules/extensions.

What version of vtcl are you using? It appears to me that the sf.net site
has, as its latest release, version 1.6.0 . Is that what you are
using?

Tcl is the name of the language implemented by the libtcl C code.
> TK is a graphical 'extension' to TCL
Tk is the name associated with libtk C code - which implements an
additional set of Tcl functions primarily associated with the
creation of graphical display behavior.
BWidgets is the name associated with a set of functions,
written in Tcl/Tk, designed to make it easier to program more
sophisticated Tcl/Tk applications by providing a set of
pre-programmed 'megawidgets' (more complex graphical items
made of combining the existing widgets plus some extra code).
> Wish is a TCL interpreter?
To execute code written in Tcl, one needs to some how interpret
that source code. Two very common ways of doing that is making
use of some programs created when one installs Tcl and Tk.
When you install the Tcl libraries, you get a stand alone
program called tclsh . When you install the Tk add on libraries,
you typically get a stand alone program called wish.
These binary programs are designed to be very crude wrappers
around the libraries - basically taking a command line argument
that represents a file name to read and interpret.

At a minimum, you will need to update the tcl and tk libraries.

It makes great sense.

No, for the time being, each Tk release typically includes a wish interpreter
for that version.

Each wish is directly associated with a version of tcl and tk.
You don't need to do anything about it.
As for the error you are getting about BWidgets, I am a bit
confused about that - I just downloaded the latest vtcl
and I don't see that that error when I point to my
version of ActiveTcl. I do get an error about not
finding Tix, but that's fine.
The error means that some how something in your vtcl
environment - perhaps something you have saved in a preference
file - is referencing a really old version of BWidgets.
Anyone else here on the list have a tip for how this
user can solve this problem?
