Thanks to all those who pointed out that REP and REPZ are the same
prefix.  I was fooled by the Intel guide "8086 ... Programmer's Pocket
Reference Guide, (C) 1980, 1982" which states on page 43 that the 
opcode for a REP is #F2 and for REPZ it is #F3.  This is wrong.  In
fact, the same manual has the correct numbers (including REPNZ) on
page 25.
   My appologies to MicroSoft and Lattice.  I (and others) are still
having difficulties with movmem(), but the cause is as yet unknown.
