The part about setting the colours uses [Get Colour Escape String] and probably only works when using XWindows.

    # I do not want unrecognised commands to be executed as shell commands.
    # This minimises the difference between a script and an interactive shell.
    # But this dimisses the usage as command line shell.
    # If you want to use it as a command line shell comment this out.

I use a terminal with a black background and a green font. This results in a prompt like:

======
tclsh8.6 [Wed,  6 Jun 06:58:28 cecil@munus:~]
======

Where the first part of the prompt is redlight and the second part is white. Except when the user is root: then the first part is white and the second part is redlight.

I can do:
======
** 3 27
======

Which returns:

As always: comments, tips and questions are appreciated.
