Your criteria are quite complicated.

But you should check out -tsspell- from SSC. The code will
look something like

tsset pid month
tsspell, fcond((L.month == . & empl == 1) | jobchange == 1 |
n_empl != L.n.empl)

but I think your missing values could prove problematic.

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
