Nick - Thanks for your suggestion. I thought about making my own version of
-tabdisp- and putting this in, but I can't find code for tabdisp.ado in the
ado folders of Stata. Do you know if it exists as part of some larger file? 

Al

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] }
