Managing Data in a DISP (Display) Window

7-13

Managing Data

Closing a DISP window

Closing a DISP window is a simple, two-step process.

1) Make the DISP window that you want to close active (see Section 3.4,

The

Active Window, on page 3-21).

2) Press

Note that you can close a window and all of its children by closing the original
window.

Note:

The debugger automatically closes any DISP windows when you execute a
LOAD or SLOAD command.
