and is Copyright (c) Tony G. Papadimitriou <tonyp@acm.org>
All code is primarily meant to be examples of programming in Assembly Language
using the (possibly unique & non-portable) features found in the specific
assemblers mentioned below. When I say 'examples' I do NOT mean useless
incomplete code. If all required #INCLUDE files are present, you'll get a clean
assembly. Much of this code is used in real-world applications.
Each file may contain code within one or more #IFMAIN .. #ENDIF blocks. This is
not going to be included in your apps. It's only meant to demonstrate how to
use the various library functions, and to give a clean compilation of the file
if assembled stand-alone. (This makes it easier to test under a simulator, and
for certain modules, even on a real MCU.)
Note: You can 'grab' code by doing CTRL-A/CTRL-C while viewing the related page,
then doing a paste (CTRL-V) into your favorite code editor.
(Formatting should be maintained but colors may be lost, depending on the
editor used, and its related configuration.)
Disclaimer:
All code assembles correctly using the latest version of the related MCU
assembler, and has been tested and found to work without problems.
Nevertheless, correct operation is NOT guaranteed, and no warranty is
assumed under any conditions, or for any purpose.
