Not only -summarize-, but most statistical commands leave their results behind. Just type -return list- after any command such as -centile-, -ci-, -pwcorr-, -correlate-, -ttest-, -tabulate- etc. to see what is there. For estimation commands, it's -ereturn list- and results will be store in e(). Same principle. Note also the availability of scalars (-help scalar-) which can save numbers in higher precision than local macros.
