Long ago someone on this list mentioned this guy:

options dsoptions="note2err" ;

Not sure what-all it does (where is this documented?), but it definitely produces ERRORs for undeclared variables. I think it does likewise with type coercion, but am not sure. It's in my new-sas-program header template...

HTH,

Hi All - I have a simple question I've never seen answered for SAS. Many programming languages have options to force strict variable declaration and flag accidental type-o's more quickly, such as a variable used in only one spot of a program. In VB you have "Option Explicit" or in perl there is "use strict" or "use warnings". Are there any comparable options for SAS programs?

Thanks Marc
