[gradsusr] Grads on Macs vs. Linux Machines

[Rick Danielson]

Hi Marjahn,

      Are you both using 64-bit processors?
http://www.computerhope.com/issues/ch001121.htm

Some years ago, data transfer (such as by ftp) required
"binary" mode.  That's no longer true (I hope) but if you
are out of options, it might make sense to send the file
back and ask your colleague to compare the two.

Cheers,
Rick
