Not sure if I understand properly, but if your array "B" was of the
form B=bytarr(4,64,64), then doing A= long(b,0,64,64) would turn
each 4 byte chunk into a long word. Check the documentation for
the "offset" argument to "long" (and float and fix etc). If that's
what you want, then try using "transpose" to get "B" into the proper
shape.
