Syntax



   RK                        CM registers
   GRK                       NM general registers
   SRK                       NM special registers
   PK                        Program, current mode
   CMPK                      CM program
   NMPK                      NM program
   QK                        CM frame,  Q relative
   SK                        CM stack,  S relative
   GK                        Group window
   UK    [win_number]        User window
   VK    [win_number]        Virtual window
   ZK                        Real memory window
   LK                        LDEV window
   TXK   [win_number]        Text window

This command removes a window from the screen. It does this by setting the length of a window to zero lines, which effectively makes it disappear. The command permanently deallocates text, user, and virtual windows. (Attempts to set the lines to a value greater than zero for these window results in an error since the window no longer exists.) If the window is a text window, this command closes the file.

Parameters


win_number

The window number for a specific user window (U), text window (TX), or virtual window (V). If win_number is omitted, then the current window is used. The current user window is marked by an asterisk, and the current virtual and text windows are marked in inverse video.

Examples



   %cmdebug > PK

Kill the (current mode) program window.

   %cmdebug > PL 6

Bring back the program window. Remember, killing a window sets its length to zero.

   %cmdebug > VK 3

Deallocate virtual window number 3. This window cannot be brought back by changing the window length as in the above example. Once a virtual window is killed, it is gone until a new VW command is used to create a new one.
