Hi there. I have a 128x128 array of bits which I would like to randomize in a reasonably efficient way. Currently, I'm doing it in what is probably the stupidest way possible: I'm calling RANDOM 16384 times and storing the results individually--this takes about 2 seconds. I've contemplated randomizing a huge bignum and slicing 16384 bits out of it, but I can't figure out how to efficiently map those bits onto the array elements. Anyone have any ideas, suggestions, etc on how to solve my problem? I'm running a 3640 under Genera 8.1.1. Thanks for any input. SMBX forever.
