Just a quick question;

If you create a structured LinkedList or Map (Either standalone, or part of a structure) do they automatically get released (memory freed) upon program end, or they lose scope (defined in a procedure)?

Just want to be sure,

Thanks

All memory is freed automatically when the program ends.

At the end of the procedure, all linked lists and maps are freed automatically. But manually allocated memory is not freed. So if you have a structured linked list with pointers inside the structure, the memory pointed to by the pointers is not freed.

Edit: With pointers it must be freed:

Code: Select all

Structure Struct
  *Memory.Character
EndStructure

Procedure Test()
  NewList L.Struct()
  AddElement(L())
  L()\Memory = AllocateMemory(1000)
  AddElement(L())
  L()\Memory = AllocateMemory(555)
  AddElement(L())
  L()\Memory = AllocateMemory(789)
  
  ; Free allocated memory
  ForEach L()
    FreeMemory(L()\Memory)
  Next
  ; List elements are deleted automatically
EndProcedure

I presumed as much, but always good to get confirmation.

Thanks
