After I generated the data anew, I am at least sure that the number of tabs
is ok.
Anyway, there must be something wrong with the data, maybe a meta character:
The data looks like that:
First row
' ( ) , - ... 1920 1932 1939
1940 1945 1956 1960 1979 1982 1984 1985 1987 1988
1989 1990 1992 45 : Aachen Abb. Abbau
etc. etc.
Next rows to the end:
,#die and by tab separated numbers
zu#. and by tab separated numbers
maybe # is now forbidden?
The program works for small test data.
Regards,
Petra
