There are probably many ways of doing this, but here is way using Nick
Cox's -egenmore- (SSC, Nick Winter is attributed as the author of the
-noccur()- function used here) package:
********************
clear*
set obs 100
g crosses = " "
local cross "x"
forv i=1/ 100 {
	qui: replace crosses="`cross'" in `i'
	local cross "`cross'x"
}
// ssc install egemore, replace
egen noccur = noccur(crosses), string("x")
su noccur
********************

To every ω-consistent recursive class κ of formulae there correspond
recursive class signs r, such that neither v Gen r nor Neg(v Gen r)
belongs to Flg(κ) (where v is the free variable of r).
