Touché. That's the way we did it before DO IF was introduced. It's shorter, easier to write, and easier to get right, than the DO IF solution I gave:

>>DO IF ( P01_VAR4 > 0 ) >> AND NOT MISSING( P01_VAR4 > 0 ). >>. COMPUTE P01_VAR3 = P01_VAR1 . >>ELSE. >>. COMPUTE P01_VAR3 = $SYSMIS. >>END IF.

There's a lot to be said for remembering old-school styles.

Yes. Reduce your typing, make your code shorter and more readable, and be less prone to errors.
