The HelloWorld.s source file in this archive can be used as a stand-alone 
MorphOS PPC assembly example but is intended as a companion file for the 
morphzone.org programming tutorial found here - 

http://library.morphzone.org/An_Introduction_to_MorphOS_PPC_Assembly

Please note that HelloWorld.s is also intended as a reference document for 
beginner PPC assembly programmers and is therefore heavily commented.  Most 
comment lines are much longer than the traditional 80 character width of many 
source files and may be difficult to read on small displays.  

HelloWorld-libamiga.s has been modified so that linking with the vbcc 
libamiga.a file is needed to produce an executable.  

HelloWorld_optimised.s uses a simple technique to reduce program size and the 
amount of reads and writes to memory compared to the other two versions.  

The text formatting of these source files is suited for an editor or viewer 
that properly supports tabs and assumes a tab size of 8.  

v1.02 Update: The previous method of defining the __abox__ symbol was wrong.  

v1.03 Update: Aside from the addition of HelloWorld_optimised.s there is also 
              a sneaky preview of a MorphOS assembly debugger.  On many levels 
              MAD is a crude program and can only be considered as an alpha 
              release.  I would very much like to get some user feedback.
