reading data from txt file in fortran

Question

I am writing a FORTRAN program that reads data from a text file and writing it to the console. the data file looks something like this

1234567890123456 12345         


        

Answer 1

The reason is that you're specifying a width that is too small for the real numbers. Usually when the width doesn't fit, fortran will display asterisks, which happens in your case.

You have 9 digits, but you'll need at least 10, since the comma takes up a column as well. So replacing 3F9.3 with 3F10.3 should do the trick.
