Subject:      Tracking number of records processed in a SAS job

Hi.

I have 2 datasets that I am merging and then running through some variable
creation steps, all in 1 data step.  One of the datasets being merged is
unique by key and has approx. 2 million obs.; the other has multiple
records per key and has over 100 million obs.

In my data step, I have code like below...
filename "scrn" terminal;
if mod(_n_,100000)=1 then do;
  file scrn;
  put "Number of records processed -> " _n_;
end;

As expected, my SAS job is spitting out the number of records processed
every 100K records.

Question:  Does it spit out text to my terminal every time 100K obs have
been written to the output dataset, i.e. after obs from each input dataset
read, processed through the data step and written to the output dataset?
Or, does it print text to my screen after each time the SAS system has
read 100K records from the input file?

I think the answer is the former but I am not sure.
Thanks for your clarification.

Sincerely,
Satindra.
