Sorry, maybe I should have been more explicit. The data is not
unformatted but I tried that because otherwise I get an error messege:
Input line is too long for input buffer of 32767 characters.
Ben, thanks for your suggestion, but I also get that error messege
trying your suggestion.
To be more explicit, each line of data looks something like this
(where there are 2520 columns):
1.0117065e+003 1.0114794e+003 1.0112352e+003 1.0110832e+003
1.0109401e+003 ...
Thanks,
Howard
