RE: Interesting question and debate on ddl tables with date fieldsthatwill not always have a value

I understand what Eric is saying about being able to use %nullind on
variables other than database fields. That would be nice.

And, perhaps this also has merit.

Were you hoping that IBM had written the compiler so that if you tried
dsply termDate;
and if termDate was null then you'd get a messy MCH type message as if you
tried to dsply a variable that wasn't passed into the program and you
failed to check %addr on that?

So how do you recommend IBM correct this?
Add an additional H spec to generate the abort?
Change the compilation default to generate the abort, with the additional
H spec to override it?

I doubt that it is reasonable to change the language now. I just want
to emphasize that NULL is nothing at all. No attempt to use the "value"
of a NULL can lead to anything good.

Cheers,
Terry.
