Hi.
I have to create a spell file (job spell file) from a person month file.
Anyone has an idea of how to do? In my person month file I have persnr,
month, and a variable indicating the sequence number of the job (and other
variables not interesting in this case).
A small example of what I want

I have person month file which looks like this:

Persnr  month   n_job(this indicates the order numebr of the spell)
1	   1		1
1	   2		1
1	   3		1
1 	   4		2
1	   5 		2
1 	   6 		2
1 	   7 		2
1 	   8 		3
1 	   9  	3
1	   10		3

And from this I would like to create a spell file like this

Persnr  beg  end   n_job
1	  1	 3	 1
1	  4	 7	 2
1	  8	 10	 3


Thanks,
Anna
