Davis is absolutely right, just check the file once again. If you
are looking for a particular code, I would advise you to have a look
here:

It seems likely to me that your file doesn't contain what you
think it contains. Can you open it in a text editor to confirm?
Sometimes this error comes about because the very last line
in the file didn't get a Carriage Return associated with it
and IDL needs it to count properly.
Cheers,
David
