     Thanks for the links. Actually I think I derived my PS1 settings 
from an example found in some default .bashrc. I found the colors by try 
and fail, or maybe I looked at what ncurses was producing. Of course you 
don't want to use ncurses here since you want to keep a scrolling 
terminal. I eventually wrote a simple C programs which changes the 
color. It understands color names in english and french - easy to change 
to your prefered language.

     Steve can see the use I make of indentation and curly braces 
placement is non-standard, but it makes blocks more visible :-)
