Hello,
Thanks a lot for your suggestions. Actually, I had set too much memory.
I have reduced it and now the problem seems to have been solved.
Thanks again!

Dolores

Indeed, this is one of the issues raised in the FAQs on memory
allocation 
at http://www.stata.com/support/faqs/data/#mem

Can you create an extract with fewer variables?  Or perhaps run the 
analysis on a random subsample of the data? You might do preliminary 
analysis on a random subsample and then run final models on the entire
data 
set.
