Window Operations
System Debug provides window commands which allow the user to customize
individual windows:
* The size (number of lines) of each window can be set individually by
the user. This allows the user to give up a few screen lines from
one window in order to increase the size of another window. When the
size of a particular window is set to 0 lines, then that window is
effectively removed from the screen. The command window is the only
window that cannot be entirely removed. Banner lines (the first line
of the window) are included in the window line count. For example, a
virtual window with a length of three lines contains one banner line
and two lines of data. (Refer to the wL command.)
* Windows can be individually enabled and disabled (wE and wD) or they
be removed (killed). (Refer to the wK command.)
* Windows can be scrolled forwards and backwards to display data in the
proximity of the current location. (Refer to the wF and wB
commands.)
* Most windows can be jumped to a specified address other than the
default current address (which is based on program execution.)
(Refer to the PJ, QJ, SJ, TJ, VJ,and UJ commands.)
* Windows can be returned to the "home" position. This is defined as
the location displayed in the window when it was created. Some
windows (virtual, real, ldev) allow the user to redefine the "home"
location of the window. (Refer to the wH command.)
* Window values can be displayed in several output bases. Individual
windows can be displayed in any selected radix, such as octal,
decimal, hex, or ASCII. (Refer to the wR command.)
* The Q and S windows display addresses in one of several different
modes (either DB, DL, Q, S, or DST). The mode determines how the
addresses shown in the left column of the window will be displayed.
The default is to display them relative to the current value of the
DB register. Addresses may be displayed as signed or unsigned
values. (Refer to wM command.) In addition, these windows may also
be aimed at arbitrary data segments.
* Virtual and user windows can be named or renamed. (Refer to the VN
and UN commands.)
* Virtual, text, and user windows can be used as "current" windows.
Performing an operation on a window makes it current. In addition,
one may specify explicitly which window to make current. (Refer to
the VC and UC commands.)
* Text and virtual windows can have summary information about their
shape and location printed with the "info" (wI) command.
* Text windows may be scrolled horizontally to view text in files wider
than 80 columns. (Refer to the TXS command.)
