Bob,

you aren't missing anything.

I already have some basic knowledge of  the various RPG opcodes like %DIFF,
xxxDUR, etc. but my main program is in MI and not in RPG. I already solved
the problem by calculating the object aging in another way but I'm still
interested in seeing how the MI/CDD works.

(isn't this the MI forum ?)

The sample code has been posted in RPG just to make it easier to understand
the CDD.

Giuseppe.
