This storing title on a stack stuff is something very few terminals support. Recent xterms does, but few if any others. You're right my testing confirms that. I used the official termcap info from urxvt (needed some reformatting to use it) and it didn't fix the problem. Other terminals will at best have sequences for set title and read current title. Unfortunately the sequence to return the title seems to be implemented (it returns the surrounding sequence as described in http://invisible-island.net/xterm/ctlseqs/ctlseqs.html), but the string in there is empty. I contacted the main developer of rxvt-unicode with my problem. I figure the stack solution is the most traditional and convenient approch in my opinion.

backup terminal title
I just started to wonder how portmaster changes the window title of my terminal and why it doesn't change it back when it terminates. Some digging in the portmaster code showed up an escape sequence: printf \033]0;%s\007 YOUR TEXT GOES HERE Unfortunately I am entirely clueless as to how one could backup the old title string to restore it upon termination.

I added a push/pop stack for xterm last year which can work around that (transparently). I used that in vile (vi like emacs), and I made a fix for 'screen' which uses it. see http://invisible-island.net/xterm/xterm.log.html#xterm_251 For other terminals - some have disabled the objectionable feature, some have not.

Sets the window title to 'u...@hostname:/current/directory'. Porting
this escape sequence to other shells left as an exercise for the student.

Already experimented with that, but it makes tcsh believe the prompt
is longer than it really is. So it will blow up when you move your
cursor around in long commands.
Also this doesn't really relate to the question, does it?

I realize my wording should be clearer.
I wish to use the \033]0;%s\007 sequence in a shell-script to set
the title of a terminal. But only if I am able to undo it.
My requirement is that this must be done without using anything
outside the base system.
