I did what jon suggested and it worked.
but... I got the following msgs.
error: plot: no data to plot             
 "(some how it cannot read the data)"
error: evaluating if command near line 56, column 2
error: evaluating if command near line 55, column 7
error: evaluating while command near line 44, column 5
error: evaluating if command near line 30, column 3
"(there is no if and while commands there)"
error: called from'_plt_' in file '/usr/share/octave/2.1.71/m/plot/_plt_.m'
error: called from'plot' in file '/usr/share/octave/2.1.71/m/plot/plot.m'
error: near line 135 of file '/cygdrive/c/plates/read_hayde.m'
line 135 has   'plot (date, mag_OJ - mag_f1, "04")'
Also if you have an input txt file like
1.23 233
1.34 949
1.45 345
how can I read the data??

But the script Hayden posted was not a data file. It was a script
file. So instead of loading it, you just need to make sure it is in a
directory in the LOADPATH (like the same directory where you are
running Octave; type pwd at the Octave prompt if you are not sure
where you are) and type the name of the file (without the .m):

octave:1> read_hayden
