I have just try the method which you and Mark told me to do. It works.

My Test:

loDemo=CREATEOBJECT("UseArray")
DEFINE CLASS MyCustomObj AS Custom
DIMENSION ArrayProp(1)
ENDDEFINE

DEFINE CLASS UseArray AS MyCustomObj
PROCEDURE Init
DIMENSION This.ArrayProp(2)
This.ArrayProp[1]='Hello'
This.ArrayProp[2]='GoodBye'
ENDPROC
ENDDEFINE

END Test

But, I have another question. How to store "MyCustomObj" into classlib. I have tried 'ADD CLASS' and Class Designer. They can store the class into my classlib. Is there any method can do it?

Thanks David and Mark, your suggestion is great.
