hi,
i m using an IDE which generates .obj file as final end result.But i want hex file. so is there any converter of object to hex file. please help in this matter.

Why put this in this thread and not keep it here http://www.keil.com/forum/docs/thread10155.asp ??? And it looks -very- messy.
Whats wrong with this code ? 1) it is not indented 2) it is not commented 3) it is in the wrong thread 4) naah - the above will suffice
