OK, now for the final part, in the output file I get:

ORREL> ! use final mantime to set AVER, FLUC for output
CORREL> open write unit 1 card name cd@{C}.txt
Parameter: C -> "2"
At line 145 of file /home/themis/c39a2/source/util/parse.src (unit = 5, file = 'test.inp')
Fortran runtime error: Sequential READ or WRITE not allowed after EOF marker, possibly use REWIND or BACKSPACE
OPNLGU> Unit already open. The old file will be closed first.
VCLOSE: Closing unit 1 with status "KEEP"
VOPEN> Attempting to open::cd2.txt::
OPNLGU> Unit 1 opened for WRITE access to cd2.txt

I think this is the clue, but how do I interpret it?
