    At the Local> prompt just enter:
    
    Local> Set Forward <Ctrl>~
    
    Thus pressing <Ctrl>~ at any time will forward you to your next session.

    Yes, that's what I'm doing but in addition I have to refresh my
    data entry Screens. Now is there a way to define just one key for
    the <Ctrl>~ and <Ctrl> w, without having to change my TDMS code.

    How about using UDKs? If you have a modern terminal (i.e. one with
    an LK-201 keyboard) you can have User Defined Keys. Take a look
    at the VT200 Programmer's manual. (Can't find mine right now, otherwise
    I'd post the escape sequences here).
    
    Good luck,

    Or get a really modern terminal like a VT330 that will run multiple
    sessions.  Or hack a VT-240 into an -MX to make it support sessions.

    I have a program that will load the UDKs on a VT-2xx terminal:
    (following the form-feed)

        good	= FALSE;
	while(!good)
	{
		printf("Enter key to program (Fxx): ");
		gets(line);
		if(strlen(line) == 0 || strcmp(line, "exit") == 0 ||
			strcmp(line,"EXIT") == 0)
		{
			good	= TRUE;
			continue;
		}

Go into terminal SETUP/KEYBOARD/ANSWERBACK (assuming that you use a
VT200 series terminal) and set the answerback message to <CTRL>~ <CTRL>W
(and save that). Now when you want to change the session, just type
<CTRL><F5>. That sends the answerback message to the host and does what
you want.
