Subject: Job spell sortid

I have a file with the variables persnr, month, empl(dummy var for employed/non employed), n_empl (indicating the order number of employment spells)
jobchange(indicating the month in which there is a job to job change, which is not recorded as employment spell, because an employment spell is defined when there is a non employment spell in between two jobs, so in case one go from a job to another job without going out of employment, I have only one employment spell, but I want to have 2 job spells)

I want to create a n_job variable (see below), indicating the order number of job spells. How can I do?



pid  month	empl  	n_empl	jobchange 	n_job
1	1	1	1		.	1
1	2	1	1		.	1
1	3	1	1		1	2
1	4	1	1		.	2
1	5	1	1		.	2
1	6	1	1		.	2
1	7	1	1		1	3
1	8	1	1		.	3	
1	9	1	1		.	3
1	10	1	1		1	4
1	11	1	1		.	4
1	12	0	.		.	.	
1	13	0	.		.	.
1	14	1	2		.	5
1	15	1	2		.	5
1	16	1	2		1	6
1	17	1	2		.	6	 


Thanks,
Anna
