Simon,

You should edit the temp2 line in the loop to read:

gen temp2=1 if entry<exit[`i'] & exit>exit[`i']

if you want to exclude have cases of 6's that enter after `i' and exit
before `i'.  Again you may wish ">=" depending on how you wish to deal
with exits that occur in the same time period as `i'.

--Carole


gen temp1=(size==6)
gen new=.
local n=_N
qui forvalues i = 1/ `n'  {
       capture drop temp2
       capture drop temp3
       gen temp2=1 if entry<exit[`i']
       egen temp3=sum(temp1) if temp2==1
       replace new=temp3 in `i'
}
