Re: st: RE: Large data set that won't open

[John Antonakis <john.antonakis@unil.ch>]

Hi:

So, I am now running Stata with 6GB RAM and I don't have problems 
opening very large data sets. The problem was that I mistakenly was 
running Stata 32 bit, instead of 64 bit. The latter can better handle 
"giving"  RAM to Stata. With Stata 32 bit, I was unable to give more 
than 1GB RAM to Stata; now, I am able to give it lots more.

Best,
J.
