Hi,

I have 1000 records data and need to select certain number of rows from the data.

for e.g - I want to extract observation/row no . 5, 21, 58, 84, 134, 367, 412, 498, 578, 634.........

Hi,

If there is no pattern in the number of rows you want to extract, then you have to conditionally check whether _n_ system variable hold required row numbers. If yes then extract.

If _n_ in (5,21,....);

Generate a data set with 1000 numbers.

Data Random_data;

  do num = 1 to 1000;

  OUTPUT;

  end;

RUN;

Use POINT= option to read only those records from the above data set - Random_data;

Data random;

  do i= 5, 21, 58, 84, 134, 367, 412, 498, 578, 634;

  SET Random_data POINT=i;

  OUTPUT;

  end;

  STOP;

RUN;
