Scrolling through the physical windows

You can scroll through the physical windows by using commands or PF keys. Either way, the placement of the cursor plays a key role in determining which physical window is affected by the command.

To scroll through a physical window by using commands, do the following steps:

  1. If you are going to scroll left or right through the Monitor value area of the Monitor window, enter the SET MONITOR WRAP OFF command.
  2. Type in the scroll command in the command line, but do not press the Enter key. You can enter any of the following scroll commands: SCROLL LEFT, SCROLL RIGHT, SCROLL UP, SCROLL DOWN . You cannot scroll left or right in the Memory window.
  3. Move the cursor to the physical window or area of the physical window you want to scroll through. In the Memory window, move the cursor to any section of the memory dump area. In the Monitor window, move the cursor to the Monitor value area to scroll left or right through that area. If you did not enter the SET MONITOR WRAP OFF command, then the scroll command will scroll the entire window.
  4. Press Enter.

If you scroll a window or area to the right or left, z/OS® Debugger adjusts the scale in the window or area to indicate the columns displayed in the window. If you scroll a window up or down, the line counter reflects the top line number currently displayed in that window. In the Memory window, if you scroll up or down, all the sections of the memory dump area adjust to display the new information.

You can combine steps 2 and 3 above by using the command to indicate which physical window you want to scroll through. For example, if you want to scroll up 5 lines in the physical window that is displaying the Monitor window, you enter the command SCROLL UP 5 MONITOR.

To scroll through a physical window using PF keys, do the following steps:
  1. Move the cursor to the physical window or scrollable area you want to scroll through. A scrollable area includes the memory dump area of the Memory window.
  2. Press the PF7 (UP) key to scroll up or the PF8 (DOWN) key to scroll down. The number of lines that you scroll through is determined by the value of the Default scroll amount setting.

If you do not move the cursor to a specific physical window, the default logical window is scrolled. To find out which logical window is the default logical window, enter the QUERY DEFAULT WINDOW command.
