    Write a fake version of your assembly routine in C: same calling
parameters, etc.  Make sure your fake code refers to each of the calling
parameters the way you expect to.  Compile the module with the /Fa
option, and the compiler will produce a source assembly file, suitable
for hacking.  All questions about referencing variables will be answered.
