Thank you for your responses. I am running the following specs:
Stata 10.1
MS Win XP, SP3
On a 1.1 GHz, 1.93 GB RAM Processor
I think my limitations may be the cpu... The most memory it will grant
is 1g, and its not enough.

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

2010/5/6 Nate Breznau <[email protected]>:
I am wanting to end my usage of SPSS, and in general have successfully
done
so; however, in a project working with U.S. Census data I need to use a
datafile that has over 30 million cases and 15 variables. This is the
smallest version I can use for my purposes. Is there any way to alter
Stata
to work with such a monster file? I've pushed it to its maximum allowed
memory and its not enough.
I thank anyone kindly for any advice, no matter how dismal.
-Nate
