BASIC languageLists

PopListPosition

List command

Syntax

Makes the element saved by the last PushListPosition() current again, and removes it from the stack.

PopListPosition(<list>())

Parts

<list>A list declared with NewList, written with its empty parentheses: scores().

Good to know

  • Returns nothing: write it on its own line.
  • With an empty stack, the program stops with "BASIC list position stack is empty".
  • If the saved element was deleted in the meantime (by DeleteElement(), ClearList(), SplitList()…), the program stops with "Remembered BASIC list element no longer exists".

Example

NewList a.integer()FOR k = 1 TO 3  AddElement(a())  a() = kNEXTFirstElement(a())PushListPosition(a())LastElement(a())PushListPosition(a())SelectElement(a(), 1)PopListPosition(a())Console(Str(a()))   ' 3PopListPosition(a())Console(Str(a()))   ' 1
