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.)
