You can create another reusable part which extends the functionality of the date display reusable part #EOEXAM04.
To see how this works, create a reusable part (in this example it is called #EOEXAM05). Make its Ancestor the date display reusable part (EOEXAM04) created in the previous section.
Make the Group property of the part "Dates & Times".
Note that apart from the BEGIN_COM statement your reusable part does not contain any code:
FUNCTION options(*DIRECT)
BEGIN_COM role(*EXTENDS #EOEXAM04) HEIGHT(29) WIDTH(492)
END_COM
However, even though not visible in the source code, it inherits all the functionality of its ancestor. (If you want to test this, compile the reusable part, put it in a form and compile and execute the form.)
