RE: Why RPG IV Sucks -- RPG400-L

Yes, or bottled water or radios or cars--about the same level of similarity
to %NULLID as subfiles.

One issue with this approach is that nobody understands it, it isn't well
known, and it is virtually never used.

Glad people didn't feel that way when subfiles first came out.

LOL!

If %NULLIND(Date) = *ON
  // Your date is meaningless!
/endif

One issue with this approach is that nobody understands it, it isn't well
known, and it is virtually never used.
Also even if the null indicator for the DATE field is *ON, you can still 
use
that field without restriction. That is no notification is sent if you now
move or multiply that null date with another field.
Why? Because the null indicatory is separate from the data.
Not a good solution at all in my view.

Sure they do Bob.  It's called Null support.

I would expect a *MDY date value to be able to hold Jan 1, 0001 just like
*ISO does. Under the covers they are all the same date values. 
So the valid date range should NOT have been restricted based on format
(this is not a RPG issue, however). Instead, the date fields, when viewed,
should issue a "Date out of range for format" but continue to be usable by
code for date math and for moving to *ISO and non-*ISO format dates.
Sure date's should have a "zero-like" value or *LOVAL equivalent, but 
sadly
they don't.

It would be nice if at run time the system could recognize *loval 
equalivence between different date formats and convert accordingly.
If I move a *ISO *loval to *MDY field I would expect a *MDY *loval 
of 01/01/40 from 0001-01-01.
