Please Andy Neil if you have nothing to say except offensing so save your words to yourself

from your profile:
Technical Skills: Assemply programming for ... 8051

and you have a problem understanding DS!

Andy do not try to offend you, he just tries to get you to state your problem rather than your impression of what the case may be which you clearly state in an incorrect way.

If you can not handle being told you are wrong, why ask?

Anyone here will gladly help you, but very few have the patience to argue back and forth to get rid of wrong impressions.
