Dear Eli:

Thank you very much for your message below. 

I found the characters you mention, therefore I think the problem has to
be what you suggest. 

The first occurrence is in the file header, which has the number 10 as
integer*4. Where it should say 000a it says 0a0d. And there are more.
The file size is 4143 bytes (I said 4137 before). It should be 4136.
I find five occurrences of the combination 0a0d, using od -h
<binaryfile>. 

Other people who also sent me mail do not have the problem, as they use
more recent versions of g77. So I conclude I have to do that, use a
newer version.

I am glad to see that the error is detected, and the problem will be
solved as soon as I get a new version.

Thank you very much for your help.

My best regards,

Marta
