Hi Paul and Todd,

>to the core McIDAS installation. Here is the way I did it: 
>-> Uninstall and unmake of McIDAS 2002
>-> Uncompress and untar the Mcidas 2002 distribution file
>-> Remove the McIDAS 2002 distribution file to prevent the shell script from
>seeing it. 
>-> Moved the original tcl & tk directories to tcl8.0.4 and tk8.0.4
>-> Uncompressed and untarred tcl8.4.1 and tk8.4.1
>-> Moved these directories to tcl and tk 
>-> CD to the src directory and copy in the four routines you modified and

>-> export CC=cc (because I'm still running and compiling under HP-UX10.20)
>-> Run the McIDAS shell script make and install.

Right.  A number of private commands that I was using were moved into
the unsupported list.  My solution was much the same as the one recommended\
in http://mini.net/tcl/3670, but it is a little more backwardly compatible.
I added the following to my code:

    # Tk widget commands moved to namespaces with version 8.1 and higher
    # Expose the old private Tk commands.
    if { $tk_version >= 8.1 } {
      ::tk::unsupported::ExposePrivateCommand tk*

So, if one decides to keep using Tcl/Tk 8.0.4, s/he does get an error
when trying to execute '::tk::unsupported::ExposePrivateCommand tk*'.

OK.  I made similar changes in these files for my distribution.

My MCGUI was not this free of use of old, private commands.  That is why
I exposed all of the commands listed in unsupported.tcl.

Since I don't use the GUI, I am relying on you to have found all of the

Part of this process is my updating the SSEC CVS with the code mods
that I made.  I will start this process (which is time consuming)
