  The assembler wont let you do that.  Using "equ" allocates a value to
the variable name.  If you subsequently use that variable name, you will
be referencing a memory location whose address is the value you
allocated.  You will encounter two faults as a result, firstly that you
have tried to clear memory locations before you told the compiler where
the locations were, and also that the second and third locations are
neither directly accessible, nor exist as memory.

  Before attempting to start with your own project, it will be necessary
to study and work through, a *lot* of examples.  Look up James Newton's
site.

  Where they are related by powers of two, you can by performing simple
rotates to divide or multiply by two.
