[albert1981]

Hallo everybody,

I would like to know how can I take a value from a text file like this in fortran:


text
number text number

output

How can i do if I want to search for the value 3.000?

Albert

Albert,

Surely a free format read statement can be used here:-

Read(5,*)I,A,B

will happily read each line of your file
