[Gambas-user] Array.Sort

[T Lee Davidson]

Hi Lewis,

You're forgetting, like I often do, the parentheses for the method [.Sort()].

...
   XXX = TestFunction().Sort()
   DoPrint(XXX.Sort())
   DoPrint(TestFunction().Sort())

   For Each S In XXX.Sort()
     Print S
   Next
   Print "-------"

   For Each S In TestFunction().Sort()
     Print S
   Next
...
