Jorg,
If you are using $MyGreatObj in a loop or some situation where you are
reusing it you can also do:
For each ($MyGreatObj; $someDataStructure)
$MyGreatObj:=New Object
$myGreatObj:= <whatever I'm doing with it>
$someOtherObj.greatProp:=$MyGreatObj
End for each
Remember that unlike other reference items from the past (menus and lists)
when you create an object using $anything:=New Object its scope is a local
variable. So when the method that created it ends the variable is cleared
too UNLESS you assigned it to a non-local variable.
This made me curious so I just checked out how this works in the debugger:
C_OBJECT($myGreatObj) // $myGreatObj = null
$myGreatObj:=New object // $myGreatObj = {}
CLEAR VARAIBLE($myGreatObj) // $myGreatObj = null
So we can say New object initializes the object as empty and CLEAR VARIABLE
sets it to null, which is equivalent to $myGreatObj:=null.
