RE: Why RPG IV Sucks






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.
