 		 #136711 - Visit The Chart
Responding to: ???'s previous message
If you study the matrix chart of opcodes at the following link:

The Opcode Chart


You can see that many of the instructions follow a very interesting pattern that reveals the encoded nature of the opcode byte.

------------------

Mike....Are you hand coding in the direct machine code? If so get your self an assembler and work with the text based instruction set. With a little practice you can learn all the symbolic instructions and you will not have to look at The Opcode Chart anymore.
