Re: od


Hi Mark,

Thank you for your reply to my message about the od utility: I wrote:

I can understand what you are saying if I interpret it to mean that
the hex storage values on my machine WindowsNT - which I assume from
you message is a big-endian platform - are faithfully represented
by the output from the od -bcx display.

What then surprises me is that the octal representation of this
same storage is 110 124 124 120 which is what I would expect.

It seems to me that you are suggesting that the only correct
representation of the hex storage values would require od to
ouput an ascii value of THPT. I reject, and od itself contradicts, 
this interpretation of the storage values as being meaningful.

I urge you to reconsider your opinion and to modify od to 
output 4854 5450.

David
