Function for picking out the variable that's not missing

[michan22]

Dear all,

I have a dataset that have 5 date variables and only 1 date variable has value (example: date1=. date2=. date3=5/30/17 date4=. date5=.)

I want to create a new variable called datefinal that returns the date value of the variable that's not missing (so it would return 5/30/17 in the example).

Is there a SAS function for this? or do I have to use an array to do this?

Thank you!
