The file mfplain.mp ends with dump; So when mf2pt1.mp says
   input mfplain;
the mem file is dumped before the rest of mf2pt1.mp is read.
Then of course bpppix is not defined (nor is anything else
in mf2pt1.mp).

This is an error (I think). There should be an mfplain.ini that
inputs mfplain.mp and then says "dump". But mfplain.mp should not
do this itself.
