Hi Mike,

My copy of MASM doesn't reverse bytes when coding in hex. Neither did
BCAF 3.1, which uses TASM.

I converted these instructions into a clone of EXIT_VDM.COM. I attach
an assembly listing of this instruction sequence from MASM 6.11. The
DW in question is at location 0103.

Perhaps Microsoft, Borland and I are all wrong.

Regards

Dave
