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.
