1.Import an excel file, put the contents in Row 3 of all variables in their labels:

{p 12 16 2}
{cmd:.import excel using http://www.stats.gov.cn/tjsj/ndsj/2014/zk/html/Z0916E.xls,clear}{break}

{p 12 16 2}
{cmd:.labone,nrow(3)}

2.Import an excel file, put the contents in Rows 3-4 of variables A, B and C in their labels. The contents from Rows 3 and 4 are concatenated by a blank space:

{p 12 16 2}
{cmd:.import excel using http://www.stats.gov.cn/tjsj/ndsj/2014/zk/html/Z0916E.xls,clear}{break}

{p 12 16 2}
{cmd:.labone A B C,nrow(3 4)}

{phang}
3.Import an excel file, put the contents in Lines 3-4 of variables A, B and C in their labels. The contents from Rows 3 and 4 are directly concatenated without spaces:

{p 12 16 2}
{cmd:.import excel using http://www.stats.gov.cn/tjsj/ndsj/2014/zk/html/Z0916E.xls,clear}{break}

{p 12 16 2}
{cmd:.labone A B C,nrow(3/4)  nospace}

{cmd:.import excel using http://www.stats.gov.cn/tjsj/ndsj/2014/zk/html/Z0916E.xls,clear}{break}

{p 12 16 2}
{cmd:.labone,nrow(5 3 4) concat(:)}

{phang}
5. Import an excel file, put the contents in Rows 5, 3 and 4 of all variables in their labels. The contents from Rows 5, 3 and 4  are concatenated by {cmd:":"} and {cmd:"+"}：

{p 12 16 2}
