-return list- (or the reference manual [R] ttest) displays the saved
results.  You will need to save of values you want after each -ttest- as a
scalar, macro, or a variable.

One way would:

sysuse auto, clear
levelsof rep, local(levels)
foreach l of loca levels {
	ttest mpg = 20 if rep == `l'
	scalar t_stat_`l' = r(t)
}
scalar list _all


Hope this helps,
Scott
