Please ignore my last post, I hit the send button before it was
finished. (Hence the indices not being incremented, the branching not
shown, and no counter, and other stuff.)

Anyway, one reason I like to set a flag is that instead of stopping at
the first bad read,
I can keep trying to read records and count how reads set the error
flag.

Yes, that may work. I do, however, although I'm not a
portable-at-all-costs type, try to use the system call as little as
possible, since you never know what on system will someone try to run
it.
Morever, although the data lines are more-or-less of the same lenght,
the first 14 lines are not (depending on the experiment they differ).

But nevertheless, thank you for the effort.

Ugnnng, I hate this. While complicating on how to solve this, the
simple solution was right in front of me (thanks epc :-(

No, you don't need to post an example of counting :-)
The files are relatively short so going through the lines twice is not
a problem. Problem solved!

Thank you, and all whom I didn't reply.

regards
Luka
