DATE fields in RPG-IV

We are just beginning to use RPGiv here - and many of you probably know
how this should be done, so ....

We are looking to our Year 2000 changes.  This brings us to the DATE
type field, and some areas of confusion:

I read a file with numeric fields for dates which = 0.   When I try to
convert these to a date field, it results in 01/01/0001.  When I try to
convert this back to a 6,0 numeric field, it gives an error because it
must be in a date range 1940 to 2039 to convert to a 6,0.  We need to be
able to convert back to numeric format for output to display file and
printer file DDS.  How should this be handled?

thx
