creating new columns from a column

lalohg — Mon, 12 Nov 2018 19:35:10 GMT

Hi there,

I have column 1 in the attached file and wonder if you could help me with the SAS code to create columns 2 to 5 from column 1? column 2 will have the first code, column 3 the second and so on....

Thanks

1. Use COUNTW() to count the number of words.
2. Use a do loop with SCAN() to parse the items.

@lalohg Not appropriate to mark your own response. You should choose one of the two solutions you got and give them the credit!

Hi novinosrin,

I am having problems to get new columns. Like col1 in the code you sent me I have 4 more columns from which I would like to separate the codes, the names of all columns are:

codcau21

codcau21
codcau31
codcau41
codcau51

When I run the code below:

data test2;
set Def2009_2017; /*(this data set has more than six million rows)*/
array disease1(5)$4; do _n_=1 to countw(codcau21); disease1(_n_)=scan(codcau21,_n_,' ');end;
array disease2(5)$4; do _n_=1 to countw(codcau21); disease2(_n_)=scan(codcau21,_n_,' ');end;
array disease3(5)$4; do _n_=1 to countw(codcau31); disease3(_n_)=scan(codcau31,_n_,' ');end;
array disease4(5)$4; do _n_=1 to countw(codcau41); disease4(_n_)=scan(codcau41,_n_,' ');end;
array disease5(5)$4; do _n_=1 to countw(codcau51); disease5(_n_)=scan(codcau51,_n_,' ');end;
run;

I get the following error message in the log window:

49 data test2;
50 set def.def2009_2017;
51 array disease1(5)$4; do _n_=1 to countw(codcau21); disease1(_n_)=scan(codcau21,_n_,' ');end;
52 array disease2(5)$4; do _n_=1 to countw(codcau21); disease2(_n_)=scan(codcau21,_n_,' ');end;
53 array disease3(5)$4; do _n_=1 to countw(codcau31); disease3(_n_)=scan(codcau31,_n_,' ');end;
54 array disease4(5)$4; do _n_=1 to countw(codcau41); disease4(_n_)=scan(codcau41,_n_,' ');end;
55 array disease5(5)$4; do _n_=1 to countw(codcau51); disease5(_n_)=scan(codcau51,_n_,' ');end;
56 run;
