A TEST version of MFF10 is archived here in this file. Use MFF10 in place of MFF120 (provided in the file MFFCP.AR) when the latter issues an error message about the MFF1 input file being too big and needing too much memory. MFF10 permits us to convert MFF1 to MFF0 no matter how big. But it does this at a price: it can take a very long time to convert a MFF1. Please read the documentation -- I still need help. -- thx, Paul Seniura.
