pltext: Switch to text screen 

DESCRIPTION:

	Sets an interactive device to text mode, used in conjunction with
	plgra to allow graphics and text to be interspersed.  On a device
	which supports separate text and graphics windows, this command causes
	control to be switched to the text window.	This can be useful for
	printing diagnostic messages or getting user input, which would
	otherwise interfere with the plots.  The user must switch back to the
	graphics window before issuing plot commands, as the text (or console)
	device will probably become quite confused otherwise.  If already in
	text mode, this command is ignored.  It is also ignored on devices
	which only support a single window or use a different method for
	shifting focus (see also plgra). 

SYNOPSIS:
