!setproperty()
Prototype
!setproperty (
type(*) objectpropertyvalue
Return value
.nul
Description
Sets the value of a property of an object, using the property object
for the type, and the object itself. This can be useful if you are working
with an unknown object, and wish to assign a value to one of its properties.
Using the type object the properties can be retrieved and now
with this function the values of those properties can be assigned. Without
this function, the name of the property must be known at compile time in
order to assign a property's value. This is also the only way that a property
that has been marked readonly can be set. In such a case,
the read only property must be set in a member function of the type and it
can only be set using this system function.
