I will cede to Leo that the recently distributed iff.library is not
the ultimate word on iff, but it would do exacly what I need IF I used
Manx and not Lattice 4.01.  So, I am gonna try to Lattice-ify it.

      However, this attempt will take me into new territory.  Assembler.
Could someone please let me know if I am approaching it the right way?
I am going to pull the assembler out of the iff.h file and then try to assemble
it.  That should produce a xxx.o file that I can link with the other modules
in my program --- right?

      Will the lattice supplied asm handle that simple piece of asm source,
or do I have to change some of the mnemonics, or add some magic at the
beginning or end, or ???

                        thanks
