|The Windowing Interface|
You should be aware of the following two factors that affect your full-screen session:
|Window and PF Key Priorities|
When input is specified in more than one window, the debugger processes windows according to a sequence determined by window priorities. Generally, a window of a higher priority is processed before a window of a lower priority. The debugger sets priorities that cannot be changed. The following list of windows is in order from highest to lowest priority:
PF keys have a lower priority than any of the windows. Consequently, if input is specified in a window and a PF key pressed, the window input is processed first and then the PF key command is processed.
The only exception to these priorities occurs when
there is text after the Cdebug: prompt in the Command
window and a PF key is pressed while the cursor is inside the Command window.
In this case, the text is completely ignored and the PF key is processed.
This enables command scrolling in the Command window: you can use the PF19
and PF20 keys to scroll through or recall previously issued commands. (The
PF19 and PF20 keys are assigned the
window scroll < > up and
window scroll < > down
commands by default.)
|Number of Open Windows|
There is a limit to the number of
windows that the debugger can
display at one time. The limit depends on the type of windows that are being
displayed and the display attributes of those windows. To avoid reaching the
debugger's display limit, close windows that are no longer necessary. By default,
the PF15 key is assigned to the
window close < >
You must be especially careful with the Print and Dump
windows. Directing output to these windows with the > command prefix causes
a new window to be opened. It is possible to open a large number of these
windows at one time, each of which overlays the previous window. When either
command is used in conjunction with the
command, it is easy to open a large number of windows.
