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

   UW  m                       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.)

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.

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

   $nmdebug > TXW TGRADES.DEMO.TELESUP
