[REBOL] [REBOL] Default Port Values? Re:(2)

[tim]

Hi Ladislav:
        Yes, your code works for me. But I wrote a function
as follows:
safe-close: func [p[port!]][if p [close p]]
lets say  
dufus: none
safe-close dufus
generates
Script Error: safe-close expected p argument of type: port
HOWEVER:
if I write 
safe-close: func [p][if p <> [] [close p]]
dufus: []
safe-close dufus
I get no error message.
:>) Duh!! I know I have lots to learn yet.
Thanks
Tim
