sum is a reserved word for an already existing function.
So you can not use is for a variable.

Try this:

octave:2> mydata=dlmread("wierd.dat")
mydata =

    9
   10
    2
    3
    2
    3
    2

octave:3> sum(mydata)
ans =  31

Look on "dmlread" and also "load" help to understand how to
load a file in a variable.
