Thank you Carole,

it works very well. I tried several solutions by myself but I was far
away from 
fixing the problem - I really appreciate!

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'.
