Hi Sunbow,

Instead of reading just the first few observations you also might want to use a more representative (stratified or not) sample. E.g.:
DATA Selection;
  SET Complete (WHERE=(UNIFORM(-1) GT .99));
  ................................;
RUN;

Regards - Jim.

Hi,
I have a large sas dataset from which i wish to read only a few observations just to test my code.

I know, if the data resides in an external file one could use in file and obs=number to read few observations. Is there a way to read few observations from sas dataset?

Any help is appreciated.
