Open a FITS file on either disk or tape. If reading from or writing to disk you may specify whether the data bytes are (to be) reversed (i.e.in standard IBM order, highest to lowest) or (to be) left as is (i.e.standard VAX order, lowest to highest) -- IBM order is the FITS standard. If writing to tape you may specify the blocking factor (greater than or equal to 1) and whether data is to be written at the start of the tape (default) or appended to the end.
