LittleEndian help

Hi. I am reading binary data.I know that it was made on a AIX machine and is
bigEndian, so I made the following script to extract the data, which
includes the line
setfileoption("bin","ReadByteOrder","LittleEndian")

At the end of the script, I use the printMinMax function to look a the the
data and I can see that the setfileoption did not fix the data.
am I missing something?

Thank you ahead of time for the help.
Sincerely,
Erik
