Thank you guys! Now you see how much of a begginer I am.

But now I get a compiler error that looks very strange to me:
C:\(...)\SequDoc.cpp(79) : error C2227: left of '->CreateNewFrame' must
point to class/struct/union
C:\(...)\SequDoc.cpp(83) : error C2227: left of '->InitialUpdateFrame'
must point to class/struct/union

This is the code, with the troublesome lines marked:

BOOL CSequDoc::OnNewDocument()
    if (!CDocument::OnNewDocument())
        return FALSE;
    CMDIChildWnd* pNewFrame = (CMDIChildWnd*)
        (CSequApp::m_pEditorTemplate->CreateNewFrame(this, NULL)); // <---
    if (pNewFrame == NULL)
        return FALSE; // not created
    ASSERT_KINDOF(CMDIChildWnd, pNewFrame);
    CSequApp::m_pEditorTemplate->InitialUpdateFrame(pNewFrame, this); //

    return TRUE;

Both pointers are of the correct type, CMultiDocTemplate*. And both
are declared as public in the application class and initialized in
CSequApp::InitInstance() (correctly, I assume, since otherwise
the program could not have worked before, when I wrote the first
post of this thread).

I have tried other ways, and it seems that it's illegal to access those
member variables in CSequApp. If I try to assign the value in this way:
    CMultiDocTemplate* pEditorTemplate =
then I get "Illegal reference to data member
in a static member function".

And it's no use defining a GetEditorTemplate() function in CSequApp,
because any calls to it seem to be illegal (still don't know why).
Those give me a "illegal call to non-static member function"

It looks like it must be a big conceptual mistake on my side, is it?
