Nick and Fabrizio,
Thank you for your suggestions, but I am still having troubles in
loading the data.
I started with an empty Stata and did increase the amount of memory
allocated to the data and also the matsize, by using the following:
.set memory 726m
.set matsize 200
but the programme was too slow, and the data could not be loaded at all.
Do you have any other suggestion?
Thank you,
Shqiponja

You got three suggestions here. If you are
starting with an empty Stata, then #3 is
the most relevant.
