Dear Carmen, First, if you are using Stata 7 or 8, you will not be able to open your dataset in whole. This is because there was no 64-bit version of Stata 7 or Stata 8, and 32-bit versions are limited to 2G in theory and to about 1.5G in practice. Second, Stata 7 or 8 is not able to allocate 5G of memory. What you see is a overflow error, which truncates large values to smaller ones by loosing the highest significant bits. I don't have Stata 8, but in Stata 9 here is what happens: . set mem 5G value too large r(912); . set mem 3G op. sys. refuses to provide memory r(909); . set mem 4G value too small r(910); . set mem 1100M Current memory allocation current memory usage settable value description (1M = 1024k) -------------------------------------------------------------------- set maxvar 5000 max. variables allowed 1.733M set memory 1100M max. data space 1,100.000M set matsize 400 max. RHS vars in models 1.254M ----------- 1,102.987M Obviously, 1.1G is smaller than 4G, which was reported by Stata as a "too small" of a value. Which means that the overflow occurs somewhere about 4G (remember that 2^32 B = 4 GB). Hence the message is similar to . set mem 1k value too small r(910); The same problem is present in Stata 10 32-bit, and the error message is simply confusing: . set mem 4g value too small r(910); Perhaps a more informative error message would help in this case. If you want to use your data, use the Stata's recommendation: 1. select only the variables you need for your analysis. 2. select only the observations you need for your analysis. 3. if you need to work with such large datasets, you must switch to a 64-bit version. As for the "set mem 50G" I can only cheer your optimizm!! Not even every 64-bit OS will support that much. E.g. Vista Home Basic 64 supports up to 8GB, and Vista Home Premium 64 supports up to 16 GB of memory. Stata will not be able to request more than that. For other limits, see this page: http://msdn.microsoft.com/en-us/library/aa366778.aspx Best regards, Sergiy Radyakin On 7/30/08, carmen gamarra <carmengamarra@hotmail.com> wrote: > Tom, > My operating system is Windows XP. > What could be the solution to open my bank?
