Handling unusual number conditions

[Madhusudan Singh]

Hi

My measurement sometimes generates some unusual numbers. In the data file, 
this sometimes reads as :

 Overflow

in a column full of numbers.

Can Octave handle this gracefully in some fashion ? The way I read in data is 
to read one line at a time, and then apply str2num to that string to extract 
the numbers.

And the output of the measurement *cannot* be modified. So any suggestions 
other than that could be useful.

Thanks.
