My article was unclear: REL modules do _not_ need to be page aligned. 
They have all the information needed for arbitrary relocation. RLOAD 
merely page aligns a module because the ProDOS memory allocation routine 
(GETBUFR) happens to allocate a page aligned buffer.

If you have many small routines, you might consider collecting them into 
one object, prefaced with a jump table.

The simpler code scanning technique used by RBOOT _does_ rely on page 
alignment, but only to move RLOAD to a place with room to do it right.
