#109620 - Demo only
Responding to: ???'s previous message
Billy Fairhurst said:
In this example they do the following observation:
"The example program writes stuff into memory ONLY for demonstration purposes. You should not use this method of writing into memory in structured, high-level programming languages."
QUESTION: if thisway of writing works, whats wrong with using it?

Here's the link: http://www.keil.com/download/docs/187.asp?bhcp=1

The example demostrates the fact that you can write to all the 8051's memory areas from C51.

What they're saying is that in structured, high-level programming you wouldn't go writing direct to hard-coded addresses - you would use named variables instead.
