OK.  I realize it is not Friday!  I told you I was tired but I am now
answering my own question.

gen failure=0
replace failure=1 if orgnr[_n+1] != orgnr[_n]

note: to correct for those that did not fail and should be right
note: failreas is variable that tells reason for firm failure
replace failure=0 if failreas==.

A Friday (my brain is dead question).

I am trying to dummy code failure year.  

I have repeated observations for companies and listed failures but the
reported failure year typically doesn't match the last year of company
data so I can't dummy code if year=failureyr.  My data runs from 1994 to
2002 so most firms are right censored but I want to code a failure for
the last year of data for the firms that fail earlier than 2002.

orgnr	      year		startyr	failyr
21		1994		1994		2001
21		1995		1994		2001
25		1994		1994		1999
25		1995		1994		1999
25		1996		1994		1999

I was thinking about using the transition by organization number (orgnr)
Something like if orgnr(_n-1)!=orgnr(_n) then.... 

Thanks for your help,
