 I really don't want to start a DOU/DOW war.  I'm just curious why you are
calling it inferior. It's just a different tool.

 Example:

 C      Key     Setll   File
 C      Key     Reade   File            40
 C              DOW     NOT *IN40
 C              ... other code ...
 C      Key     Reade   File            40
 C              Enddo

 I'd like to hear your comments on this.
