 Hello all, I was not clear in my details and goal in my last post. So, I am reposting this again.

 

The data look like what I have in 'Have' above.

 

Want:

I need to find and flag records that have any value occurring after 'PB' or 'MB', if there is any non-missing value occurring after values 'PB' or 'MB' horizontally, I want to flag it.

                                        flag 
PM MM JM MM PM PB . . PM .               1
PM MM JM MM PM PB JM . . .               1
PM MM JM MM PM MB PM MM . .              1
PM MM JM MM PM PM MM MB .                0
PM MM JM MM PM PM MM PB .                0

Thank you for your time on this.
