The examples within the explasm directory show various techniques which may 
be useful when writing assembler code.  

Example utoa1.s shows Integer to String Conversion, but also shows use of 
the stack and a recursive function.  This example also uses files udiv10.s 
and utoatest.c (and optionally utoa.apj)

Example divc.c generates assembler code for dividing by a constant. One 
sample of this generated code is used in testing the above utoa1.s example.

Example random.s shows an assembler routine for generating pseudo-random 
numbers.  This example also uses the file randtest.c to test the example 
and optionally the file rantest.apj to build the example.

Example bytedemo.c shows how byte order reversal can be achieved in just 
four instructions.
