Your version:

A* objects;
objects = new A [5];
delete [] objects;
return 0;

The problem is I don't know how to store the data variables from one page to the next so that at the last page I can use it other than writing it to a file when next button fires.

CPropertySheet *pSheet=GetParent();
CPropertPage* pPage1=pSheet->GetPage(1);
pPage1->Aceess variables;//access values
CPropertPage* pPage2=pSheet->GetPage(2);
pPage2->Aceess variables;//access values

Q: What code should I add where, for my application to open both
views on a *new* document?

1) Your app overrides OpenDocumentFile() so that it displays any views beside the default.

CDocument* CSequApp::OpenDocumentFile(LPCTSTR lpszFileName) <br />
{<br />
	CSequDoc* pDoc = (CSequDoc*) CWinApp::OpenDocumentFile(lpszFileName);<br />
	if (pDoc == NULL)<br />
		return NULL;<br />
	CFrameWnd* pNewFrame = m_pEditorTemplate->CreateNewFrame(pDoc, NULL);<br />
	if (pNewFrame == NULL)<br />
		return pDoc;<br />
	m_pEditorTemplate->InitialUpdateFrame(pNewFrame, pDoc);<br />
}

2) Let your app to handle file-new command, and call the overriden OpenDocumentFile() in the command handler.

void CSequApp::OnFileNew()<br />
{<br />
    CWinApp::OnFileNew();<br />
    ... (some call to OpenDocumentFile())<br />
}

If I understand you correctly, I should change it to...
ON_COMMAND(ID_FILE_NEW, OnFileNew)
...and then define the OnFileNew function:
void CSequApp::OnFileNew()
{
CWinApp::OnFileNew();
... (some call to OpenDocumentFile())
}

CWinApp::OnFileNew();

OpenDocumentFile(fileName);

in CSequApp::OnFileNew(). Add code to retrieve the file name first and then call

OpenDocumentFile(fileName);
