d.CurrentPageLayout.FirstPageNumber = 1;
t = Text('Page ');
t.WhiteSpace = 'preserve';
t1 = Text(' of ');
t1.WhiteSpace = 'preserve';
pageinfo = Paragraph();
pageinfo.HAlign = 'center';
append(pageinfo,t);
append(pageinfo,Page());
append(pageinfo,t1);
append(pageinfo,NumPages());
append(footer,pageinfo);

% Create several pages.
p = Paragraph('Hello World');
append(d,p);
p = Paragraph('Another page');

append(d,clone(p));

close(d);
rptview(d.OutputPath);
