System Debug Reference Manual
wW
Defines (enables) new windows.
Syntax
VW virtaddr [name] Virtual window
ZW realaddr Real Memory
LW Ldev.off LDEV (Secondary Storage) window
TXW filename Text window
UWm User window (see UWm command)
The VW and TXW commands allocate the next available virtual (V) or text
(TX) window. The window is aimed at the specified address (V) or file
(TX). Finally, the window is marked as the "current window."
The LW and ZW commands aim/enable the real memory window (ZW) and the
LDEV window (LW) respectively. There is only one of each of these
windows.
By default these windows are created with an initial length of three
lines (one banner line and two data lines). The size of the windows may
be changed once they are created (Refer to the wL command.)
Parameters
virtaddr The virtual window can be aimed at any Precision
Architecture space and offset address. Virtaddr can be
a short pointer, a long pointer, or a full logical code
pointer.
name This is the name with which to label the virtual window
being defined. If no name is specified, "Virtual" is
used as a default.
realaddr The real memory window can be aimed at any real address.
Ldev.off The LDEV window can be aimed at any valid disk LDEV
number at a specified byte offset.
filename The file name to which the text window is aimed.

$nmdebug > TXW TGRADES.DEMO.TELESUP
