I just include $WINDOW (which is defined in the environment by screen)
in bash's PS1 (prompt) variable.  E.g.,

if test x"$WINDOW" != x""; then


This results in the prompt looking like (for screen window 1):


What I want to do is instead of it showing the number of the screen, to
have it show the title I've assigned that window via C-a A.  All I need
in order to do this is to know how to access that information from
screen given the $WINDOW number (I can use bash's $PROMPT_COMMAND to set
PS1 dynamically).  E.g.,:

I played around with this but couldn't seem to get it to react - is this
for setting the title in an xterm?
