Hi, i wrote you to your cpan.org email. I attach a sample of my .rep file. I don't know if the problem is that i am processing a unix file under windows or dos structure files. In the other hand, during de process the record one has a very good extraction, with the same lenght that the header especified. Then i asume that the problem is not the file under windows system. If you prefer i can write you to your email, and attach an example. Thanks
