>Would you time the other three options too? I'm really curious and wouldn't be surprised if any of them fared better than bittest.

0.026 - the "array[256]" method - 5 times faster than bittest, as expected...
0.266 - the "256 variables" method
0.466 - the "divide by 128,64,..." method

Test was for 10,000 retrieves.
The array and variables were defined before timing (used... "bittest" method to define them.)

Thanks for all,
