I have been experimenting with reading in binary data and manipulating it. This is my first attempt at dealing with binary data and I have a couple of questions that I was hoping someone with more experience in this area could help with.

1) I haven't found any way to do bitshifting (<< and >>). Does Rev have an equivalent function?

2) In the files I have been reading in I have to deal with signed 15 bit integers. I need to be able to read these integers as base 10 numbers and then convert base 10 numbers into a signed 15 bit integer. I wrote a small function that uses two's complement for reading them but I was wondering if there was an easier way?

3) The files I am reading store the information using Big-Endian. Let's says I was reading in a 4 byte unsigned integer. Currently I am doing something resembling the following:
-- get binary data
binaryDecode("B8B8B8B8", myBinaryData, opt1, opt2, opt3, opt4)
-- Big-Endian conversion
put opt4 & opt3 & opt2 & opt1 into opt


It doesn't seem like this is the most efficient way to do this? Any suggestions?

If anyone has tips on any of these items I would really appreciate it.

Thanks,
