How I change the number of samples in this code from 10 to 1000?

In this code how do I change the sample size of data from 10 to 1000?:

data samples;

do samp = 1 to 10;

do t = 1 to 100;

u = rannor(1996)*5;

x = 100 + 3*rannor(6991);

y = 10 + 0.5*x + u;

output;

end;

run;

Do I just change the number 10 to 1000? I just tried that in SAS and now SAS has been loading for awhile. I'm worried I got it jammed and now it's messed up.

"Do I just change the number 10 to 1000?"

That's correct

"I just tried that in SAS and now SAS has been loading for awhile."

That's not likely. Maybe you need to close and restart

201  data work.samples;
202  do samp = 1 to 1000;
203  do t = 1 to 100;
204        u = rannor(1996)*5;
205        x = 100 + 3*rannor(6991);
206        y = 10 + 0.5*x + u;
207        output;
208    end;
209  end;
210  run;

NOTE: The data set WORK.SAMPLES has 100000 observations and 5 variables.
NOTE: DATA statement used (Total process time):
      real time           0.12 seconds
      cpu time            0.01 seconds

0.12 seconds to create a data set of 100000 records with samp=1000. And mine isn't a particularly fast computer.

If you increased the value of T as well that might lead to more time. Show the code you actually submitted when testing SAMP= 1 to 1000
