Subject:      Programming help: trigger and increase by 1 within a person
Content-Type: text/plain; charset=US-ASCII

Hello,

I wanted to created a new variable. In the following data, if type='DC'  the new_variable should increase by 1. In the beginning, the variable starts with 1. Each time DC is encountered, the new_variable needs to increase. If a new person comes in, the process starts all over.

I hope that someone out there will think that this is easy to do!

Thanks,
Duckhye
