[oopic] Convert array of Bits to Byte

I have an array of three bits (based on an object being in range on a
combination of three IR sensors). Is there a graceful way to convert
this 3-bit array to a single byte value? I have written a function
that returns a value of 0 to 7 based on the status of the bits in the
array, but it uses a long and awkward series of If Then Else looping.
I was wondering if there is a simpler way to do this with version 6.1.

thanks
