dt << Journal;
dt << Layout;
You can also create a new journal window and immediately add to it within the New Window() command. The following examples create an empty untitled journal and layout:
New Window( <<  Journal);
New Window( <<  Layout);
New Window( "Sales", << Journal );
New Window( "Sales", << Layout );
New Window( "Test Buttons", << Journal,
	Button Box( "Test One", New Window( "Hi there1", << Modal ) ),
	Button Box( "Test Two", New Window( "Hi there2", << Modal ) )
);
<< Journal("Freeze All");
Similar to Freeze All but only within areas of a report called pictures.
<< Journal("Freeze Pictures");
Similar to Freeze Pictures but only within frame boxes (which are within pictures).
<< Journal("Freeze Frames");
Similar to Freeze Frames but only for the frame boxes that have scripts to draw something on them.
<< Journal("Freeze Frames with Scripts");
Current Journal() returns a reference to the display box at the top of the current journal display window. If no journal is open, one is created. There are no arguments.
Current Journal() <<  Append( Text Box( "Hello World" ) );
Current Journal()["Parameter Estimates"] << Append( Text Box( "Asterisks show items significant at 0.05" ) );
