Loop through dataset and export to csv

[current_thing]

Hello,

I have a SAS dataset that looks like this:

Col1	Col2	Color
a	01	Blue
a	01	Orange
a	02	Blue
b	01	Color
b	01	Blue
b	02	Orange

What I want to do is for each unique combination of value in Col1 and Col2 -> create a dataset and export it. So for example:

dataset1 would be:

Col1	Col2	Color
a	01	Blue
a	01	Orange

dataset2 would be:

a

02

Blue

dataset3 would be:

b	01	Color
b	01	Blue

and so on...

How can I achieve this programmatically? Thank you in advance for any help!

Much easier to create the CSV files directly without attempting to also create datasets.

Especially if you don't need the header line(s).

data _null_;
  set have;
  length filename $200;
  filename=cats('/mydir/myfolder/basename',col1,col2,'.csv');
  file csv filevar=filename dsd ;
  put (_all_) (+0);
run;

 If you do need the header line then it can also work if the data is already sorted (or at least grouped).

data _null_;
  set have;
  by col1 col2;
  length filename $200;
  filename=cats('/mydir/myfolder/basename',col1,col2,'.csv');
  file csv filevar=filename dsd ;
  if first.col2 then put 'col1,col2,color';
  put  col1 col2 color;
run;
