How can I dynamically modify the format-mask of an item ?

How can I dynamically modify the format-mask of an item ? I would change the format mask of an item : 1) default format mask : 9999"-"9999
2) other : FM99999999

When I enter a new (or modify the) value of this item, I will use the second format mask.

if "I modify then item's value" then

    set_item_property(item, FORMAT_MASK, '9999"-"9999'); else

    set_item_property(item, FORMAT_MASK, 'FM99999999'); end if;

Please post here or email me. Thanks again!
