```Dear Nick

```
```The length of study is 8 years. If the
period of work was 7 years without a
break, then there are only two possibilities:
the person did not work in the first year
or the person did not work in the last year.
```
```YES I WANT ONLY 1 POSSIBILITY NOT WORK LAST YEAR

```
```by pid : egen emplo = count(work == 1)
by pid : gen work7 = count == 7 & (work[1] != 1 | work[8] != 1)
```
I PUT EMPLO TO PLACE COUNT==7 (I don't have results if I put count==7)

but don't work. Because when I tab work7 I have obs in the wave 8 (work7==1), and is not correct in the wave 8 I want only work7==0.
my squence is 11111110

thank you very much

```I have a question about how calculate the number of years
work continuously.
I have a panel of 8 year and I want calculated the person how
has work
for 7 years no stop. (1111110)
I used this procedure:
by pid : egen emplo=count(work==1)
here work is=1 if work. after I did the tab emplo and I have
the table
for 8 years.
but there aredifferente sequence how 0111111, or 1011111 ecc and I
want only 1111110.

for ex: 1011111 but is incorrect
pid   emplo wave  work
1         7  1    1
1         7   3    1
1         7    4   1
