You have to use the foreach command, something like this:
foreach var of varlist varname* {
di "`var'"
ttest `var', by(whatever)
}
It would be nice if Stata would build this into the -ttest- command.

Hello,
I am comparing means for several variables (varname2 to varname10):
ttest varname2, by(varname1)
ttest varname3, by(varname1)
etc.
Is there a command or do file to do all these comparisons at once and
perhaps generate a summary of the results in a table?
