Help needed in replicating rows in the script

[#1]

Hello,

I need to replicate a few rows where the replicated row would have a changed value in just one dimension. I have attached a table containing some sample data:

Name	Number	Country	Start Year	End Year	AY
ABC	A123	France	2003	2006	2004
ABC	A456	France	2003	2006	2004
ABC		France	2003	2006

In my data, the dimension AY would have a value only if the column 'Number' has a value. What I need to do is, in cases where the accident year is blank, I need to replicate the corresponding row as many times as the effective duration which is the period between the end year and the start year. The output needs to resemble the following format:

Name	Number	Country	Start Year	End Year	AY
ABC	A123	France	2003	2006	2004
ABC	A456	France	2003	2006	2004
ABC		France	2003	2006
ABC		France	2003	2006	2003
ABC		France	2003	2006	2004
ABC		France	2003	2006	2005
ABC		France	2003	2006	2006

I was wondering how I could do this in the script using loops, because I have around 30000 cases in my data where I need to do the same.

Thanks and Regards,
