Then there's the question of passing a null date to a procedure. The natural impulse: ... You need to pass the null indicator along and test it separately:

In V5R4, OPTIONS(*NULLIND) was added to support passing null-capable parameters correctly. If you code this option, the null indicator gets passed along with the parameter. If the called procedure changes %nullind of the parameter, the change is reflected in %nullind of the caller.

I wish we could have just fixed this problem without requiring an option, but unfortunately, there are compatibility issues. With OPTIONS(*NULLIND), the parameter has to be passed a special way.
