Hello,
thank you for the placeholder link.
Yes, all DBI call are succesfull. I do verbosly write out the results of the queries and there are always positive right.
Like i said, if i make changes to the code (inserting a space sign) the program runs as desired (output in main and in sub goes the output file).
But in the second run, only output is writen in the main program. Verbose checks shows that the DBI calls are succesful, but the print $FILE2 statemants in the sub seems to go to nirvana.
