You can do it in two instructions.

1. Move the numeric field to the date data type field. Put *USA in
factor 1, this          tells the compiler what format the numeric field
is in.
        *USA       Move       Numfield1      DateField

2. Move the date data type field to a numeric field. Put *ISO in factor
1, this tells      the compiler what format you want the result in.
        *ISO       Move       DateField      Numfield2
You could create a procedure to do this for you.

Don't use the multiply method to convert a numeric date from one format
to another.  It is very inefficient.
