Jacob was interested in the coarser distinction between numeric and
string. 

This is just one step down the line from Austin's approach here. 

sysuse auto
foreach v of varlist _all {
	loc type = substr("`: type `v''", 1, 3) 
	if "`type'" == "str" { 
		di as res "`v'" as txt " is string" 
	} 
	else di as res "`v'" as txt " is numeric"
}

Also see help on -confirm-.

See the second entry under
help extended_fcn

or try:
sysuse auto
foreach v of varlist _all {
 loc type: type `v'
 di as res "`v'" as txt " is type" as res " `type'"
}
