sets the current window or returns its handle
INCLUDE 'iolib.h' shiftwindow(WinHandle) shiftwindow(handle)
handle(WinHandle) (i) Handle of the window that is to be made the current
handle(WinHandle) (o) Handle of the current window
If Handle is bound, shiftwindow makes the associated Window the current window. The input and output streams are set to this window. The input focus of the host is set to this window if the host servers operation system allows that. If you do want the input focus changed, you would have to use gotowindow () instead.
A runtime error occurs if WinHandle is bound but invalid.
