What do you mean by "infinite" precisely? There are various mathematical meanings, courtesy of Cantor, but I doubt that you mean any of them. 

Otherwise I can think of three answers to your question. 

1. -help limits- tells you the limits your Stata has in terms of what it can do; your machine and OS probably cannot oblige. 

2. You can set up a dataset with 30 observations and keep sending results from a loop to a file outside Stata, but in terms of doing anything with those results in Stata you are back to answer 1. 

3. What you are doing probably has an analytic solution so that computation is unnecessary. In particular, Stata's functions will surely print out a t-table better than any you can get by simulation.

I need to t-test an infinit number of random samples of size 30 ,from an
infinite,normally distributed population.Each t-value is saved and then
appended together to form a database for t table.The problem is that I get
constrained by memory regardless of the size of the memory in my Stata.I
have Version 9 .Is there a way of  getting  around this constrained.?
