Problem with file writing

Hi everyone,

I have a problem when trying to write a couple of numbers to a file: I
get artifacts ilke

10 0.359E-02
11 0.348E-02
12 0.339E-02£±_«.: 0.331E-02
14 0.324E-02
15 0.318E-02
or

84 0.239E-02
85 0.2£±_«.: 86 0.238E-02
87 0.238E-02
88 0.238E-02
in my file when I write them using write(outunit,'(I6,E15.3)') i,x
When I plot them to the screen, everything is fine.

Compiler is gfortan, system is Debian Lenny if this is necessary.
