ReturnValue for PopListPosition() + ChangeCurrentElement()

[Josh]

Most commands that change the position pointer of a LinkedList return the pointer to the new element. Unfortunately this is not the case for:

• PopListPosition()
• ChangeCurrentElement()
  Even if the new element is specified in the parameter here, a return value would be useful for a better code and for reasons of symmetry to other list commands. The parameter can e.g. come from a stack and should be stored in a global pointer after changing the position pointer.

For the same reasons, the commands

• ClearList()
• FreeList()
• ResetList()

should have a return value of zero so that a pointer can be deleted by the return value.

Agree, if possible. They already seem to return some integer values (???) which maybe are being used somehow internally...

But I like the idea. If you have the opportunity to return a convenient value, do it.

I like to return #Null on freeing too, like:

Code: Select all

*MyObject = CreateObject()
; do some stuff
*MyObject = FreeObject(*MyObject) ; now #Null
