What does >> mean???

">>" and "<<" are binary bit shift operators. "4" in decimal is equal to "0100" in binary, and "4>>3" shifts "0100" three bits to the right. The result of the operation is "0001" in binary ("1" in decimal).

I'm sorry I've shifted only two bits. The result of the operation "4>>3" is "0000" in binary ("0" in decimal).

Although that is cool, how would it even be necessary!!! (Thanks though, I get it)

It's useful for compressing data; you can store two 16 -bit numbers in a single integer by doing something like: integer=number1 OR (number2<<16) And then extract them by doing: number1=integer AND &HFFFF number2=(integer>>16) AND &HFFFF
