Register saving conventions
Procedures and functions must preserve the EBX, ESI, EDI, and EBP registers,
but can modify the EAX, EDX, and ECX registers. When implementing a 
constructor or destructor in assembler, be sure to preserve the DL register. 
Procedures and functions are invoked with the assumption that the CPU's 
direction flag is cleared (corresponding to a CLD instruction) and must return 
with the direction flag cleared.
