Deepak,

Unfortunately, there is no way to include include file rather than put #include myinclude.h at the top of the program. I don't think, if you include file in your main program, it would be visible everythere, I believe, you have to include it each time again. I have to check help on this (and you too), but I'm almost certain, that's true.
