random number generation

How can I generate 100 samples, each with 1000 random numbers from a uniform distribution(0,1)?
What is the code to find the mean of each sample and the calculate the mean of means and stand. dev. of the means?

Thanks!

ranuni()

proc means, proc tabulate, ....

I.e:
data RandomNumbers;
do sample=1 to 100;
do n=1 to 1000;
RandomNumber=ranuni(0);
output;
end;
end;
run;

And then use a procedure which allows you to calculate your values on different levels (like proc tabulate or proc means).

proc tabulate data=RandomNumbers;
class sample;
var RandomNumber;
table (sample all),RandomNumber*(mean std)*f=7.5;
run;
