drawing many simple random sample with replacement from a data

I ve my data set I call  "TES"

I want to simultaneously draw sample with replacement from it then do a regression on all the samples . I want to draw 25 different samples with replacement.

The code below is not correct. Please help.

do sample=1 to 25

proc surveyselect data=tes_  method = urs sampsize = 100

   rep=1 seed=12345 out=test;

run;

end;

Proc reg data=test; by sample;

model y=t;

run;

Re: drawing many simple random sample with replacement from a data

The syntax should be something like:

proc surveyselect data=tes_  method = urs sampsize=100

     reps=25 seed=12345 out=test;

run;

end;

Proc reg data=test;

by Replicate;

model y=t;

ods output ParameterEstimates=testParm;

run;

David Cassell's seminal paper on the subject is the best place to start.
