A less elegant solution (including a ... loop through
observations). Caution v1 .. v6 are strings!
gen var2=""
local i=1
local max=_N
while(`i'<=`max') {
local temp=var1[`i']
inbase 2 `temp'
replace var2=r(base) if `i'==_n
local i=`i'+1
}
local i=6
while(`i'>=1) {
gen v`i'=substr(var2,7-`i',1)
replace v`i'="0" if v`i'==""
local i=`i'-1
}
order var1 var2 v1 v2 v3 v4 v5 v6
