Although -disp- is an acceptable abbreviation
for -display-, -tabdisp- is the only name in
question here.
I am agnostic on this point, even though I have
on occasion been bitten by this. While you're
waiting for StataCorp to think about and possibly
do this, the check is not too difficult:
foreach v of var v1 v2 v3 {
bysort cess (`v') : assert `v'[1] == `v'[_N]
}
