See http://www.stata.com/statalist/archive/2008-04/msg01278.html and the
ensuing discussion. Some datasets are just too big, and virtual memory is
damn slow...
Note the functionality of -describe- to display information about a dataset
without holding it in mem and -db use_option- which allows you to restrict
your open statement to certain vars or cases (or both). If you find this
dialog box too cumbersome to call, write a wrapper for it along the lines of


***************
pr def uo
	db use_option
end

***************

and put it into your personal directory (-di "`c(sysdir_personal)'"-) to
invoke it with -uo- in the future...

	Tom,
My operating system is Windows XP. 	
What could be the solution to open my bank? STATA allows set memory 5G, but
seems to be not enough for the bank.
	
thanks
