Maybe you could post the first five lines of your file
for us:

openr, 1, 'yourfile.txt'
h = strarr(5)
readf, 1, h
close, 1
for j=0,4 do print, h[j]

You could also try using ReadCol from the NASA Astronomy
Library, or even READ_BINARY from IDL, although you would
think this would be so simple you wouldn't need any fancy
programs. :-)

Cheers,

David
