If then statement

[AshleyM]

Good morning,

I'd like to create a variable "usedate" where usedate will take the value of "termdate" and if "termdate" is not available it would take the value of "sentdate." While I'm familiar with how to write it in SPSS, I'm not sure how to write it in SAS.

If by not available you mean the value is missing then you could do:

if not missing(termdate) then usedate=termdate;

else usedate=sentdate;

or you could use the coalese function

usedate=coalese(termdate,sentdate);

Perfect. Thank you!
