Re: reading binary

What Mary says is possible.

Another possibility: the binary was created on (say) a big-endian
machine and you are reading on a little-endian machine:

Try
    setfileoption("bin","ReadByteOrder","BigEndian")
    u = fbinrecread (fili, 0, (/121, 5, 64,128/), "float")

or, vice versa

    setfileoption("bin","ReadByteOrder","LittleEndian")
    u = fbinrecread (fili, 0, (/121, 5, 64,128/), "float")

NCL can't currently handle 8-byte record markers, but in V6.1.1, we will have added a "setfileoption" option called "RecordMarkerSize" to allow you to specify this marker size.
