Hi , Which is best local or global variables wrt data memory ?I observed that XData size is getting reduced when I am replacing my global variable with local variable.is there any effect on internal data memory if I use local variable instead of global variables?and what about the performance? I am waiting for your valuable suggestions.. With Regards, Bhaskar Reddy bhaskar@blazeautomation.com
"if the local variable happens to be declared as static, then the lifetime will be the same"
Correct - thus showing a flaw in the original question.
"if the linker directive of NOOVERLAY is used, then the overall memory usage will be the same"
Yes.
Or optimisation level below 2:

Yes, you should be more careful in how you pose them next time.
Correct.
I was kinda hoping that the OP would realise the issue in his thinking, but you gave it away - so I doubt he'll be doing any thinking at all now.
OMG. I'm so tempted to say what I really think of what you wrote there, but I'll bite my tongue.
You believe the OP understood the nuances of what I wrote in response to your questions? genuinely?
