Ties can be tracked like this
sysuse auto, clear
gen which_min = "price"
gen min = price
qui foreach v of var mpg-gear_ratio {
replace which_min = "`v'" if `v' < min
replace which_min = which_min + " `v'" if `v' == min
replace min = `v' if `v' < min
}
subject to a constraint of 244 characters on the variable holding
variable names.
