Matthew, I'm sure that others are better qualified, but, you are right about 
NULL is NULL.  However, what that means to we humans is subject to 
interpretation and database config' settings, such as SET  ZERO on||off.  
Regardless of what one chooses:

SET NULL -0-
SET NULL ' '
SET NULL VOID
SET NULL 1234567890   --Limit is apparently 4 characters, so this NULL would be 
1234

The setting is merely a symbolic representation for we human-types.  Again, how 
it gets treated is dependent on the decision of business users and the settings 
in the database.

That being said, I think you need to press [SPACE] to have your NULL-values 
"disappear" from view.

HTH,
Steve in Memphis

Subject: [RBASE-L] - How do I make NULL truly NULL?

I imagine there's a simple way to do this but I can't manage to figure out how.

I try to use R> SET NULL ''  and it does nothing, NULL keeps whatever value it 
previously had stored, in my case that is -0- which I believe is the default.  
I want NULL to be void of any and all data, both visually and logically, not 
represented by some text I define.
