Shifting the table down in memory is not a silly idea at all.   It's
done all the time.

Subject: Shifting memory to the right

Nothing like a dumb applications programmer question to end the week.
Is there an instruction like MVCL that moves memory starting at the end
working to the beginning.  I have a table that is in sequence.  I want
to insert a new row, maintaining sequence.  That requires shifting right
the end of the table.  It would be great to just code an MVCL to do it,
but I would be overwrite data.  But if MVCL started with the last byte
and worked its way to the start, then the shift would be easy.  Does any
such instruction or function exist?

I guess I could do something silly and build the table starting at the
end of the of memory block and shift it left as I build it.
