Although you are asked _not_ to send attachments -- as I should perhaps
have reminded you in my previous post -- this one got through to me and
I found that your data -reshape- fine:
. ds
x1963 x1967 x1971 x1975 x1979 x1983 x1987 x1992 x1996 x2001
x2005
x1964 x1968 x1972 x1976 x1980 x1984 x1989 x1993 x1997 x2002
x2006
x1965 x1969 x1973 x1977 x1981 x1985 x1990 x1994 x1999 x2003
regio
x1966 x1970 x1974 x1978 x1982 x1986 x1991 x1995 x2000 x2004
. isid regio
. reshape long x, i(regio) j(year)
(note: j = 1963 1964 1965 1966 1967 1968 1969 1970 1971 1972 1973 1974

1995 1996 1997 1999 2000

The problem if there is one would seem to lie in your Stata, but I can't
say what it is.

As the file *.dta containing the dataset is small(few KB), I try to
send it attached to this message. Alternatively, such a file can be
downloaded at this link:
http://www.2shared.com/file/4425484/c1951cbd/produc.html
(perhaps, need to wait few seconds before displaying the working link
at the bottom of the page)
The command I use is
reshape long x, i(regio) j(year)
