As i show pure code definition to be codes which must not be self-modifying, What i need to know is the applications in which we can use this type of code? Ask yourself the opposite question: in what situation would you ever want to write code that did modify itself?! Can you imagine what a nightmare it would be to debug...?! :-0 Yes, there are occasions where it's a useful technique - but you'd definitely be entering the Dragon's Lair...! See: http://www.8052.com/forum/read.phtml?id=84596 Of course, you can't do it on an 8051 anyway - because an 8051 has no instruction to write to CODE memory! (well, I s'pose you could do it - but then you'd need both hairy software and hairy hardware!!) There are other reasons why reentrancy is a bad thing on 8051s... |
