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.
