That is exactly what I'm looking for, however applying your code to my
program doesnt work ( though your code works beautifully). I end up
with r503 conformability error. And also instead of a [8,4] matrix I
get a [1,24] matrix.

Moleps


capture  program drop  bif_des
program bif_des
capture drop _*
quietly des,varlist

local r `r(varlist)'
di "`r'"
tokenize `r'
local first `1'
macro shift
local rest `*'

local t:word count `rest'

tokenize `rest'
forval o=2(2)`t' {
	
	local rowname `rowname' ``o''
	gen _``o''pos=1 if (``o''>0 & ``o''<.)
	replace _``o''pos=0 if (``o''<0)
	estpost tab _``o''pos,mi
	matrix def o=e(pct)
	matrix def l=e(cumpct)
	mat A=(nullmat(A),(o[1,1..2],l[1,2])')
	mat list A
	}
mat rownames A = `rowname'

end
