Thanks for your replies again.

I have tried changing the maximum row value to a range of numbers (as low as
20!), but the same result occurs.

With regard to the latest point, the text file is fomatted as follows:

-67.45832 82.87501 0.2068079
-67.37498 82.87501 0.2068079
-67.29166 82.87501 0.2068079
-67.20832 82.87501 0.2068079
-67.12498 82.87501 0.2068079
-67.04166 82.87501 0.2068079
-66.95832 82.87501 0.2068079
-66.87498 82.87501 0.2068079
-66.79166 82.87501 0.2068079 ...etc etc...

However, when displayed in Notepad, the rectangle (carriage return?) symbol
separates each row (i.e. it is displayed as one long string and not in
columns as shown above... although the above is the result of a direct copy
and paste!). So maybe this is causing a problem? If so, is there a way of
getting round this? It would take ages to go though the text file
reformatting it and removing the symbols for example.

Any ideas would be very much appreciated.

Many thanks
Steve

Under the heading of proofread before hitting send that should read:

That is normally a problem of a file that came from a UNIX system.
There are utilities on the net to convert UNIX to DOS files. This
simply adds the CR after the LF.
