But careful with such examples: They do not say much about Nate`s problem as
you are creating the default data type after -gen- which is "float". It
occupies 4 bytes, as in http://www.stata.com/support/faqs/data/howbig.html.
Strings in particular could change the picture.

Betreff: Re: st: U.S. Census Data
This basicaly a memory problem. Stata can handle bigger data set. YOu
say nothing about your OS nor the maximum RAM of your computers
In my iMac with 4G RAM the following code works fine
. clear*
. set mem 3g
(3145728k)
. set obs 30000000
obs was 0, now 30000000
. foreach i of numlist 1/15 {
2. gen x`i'=rnormal()
3. }
.
end of do-file
