preIfEmptyListNum — integer | +calc |last
Zerlegt die (kommaseparierte) Eingabe in ein Array und liefert den Wert an der Position des Werts zurück (die Zählung beginnt bei 0 und endet bei last). Es können auch arithmetische Operationen durchgeführt werden (beispielsweise last −1). Im Gegensatz zur sonst identischen Funktion listNum wird preIfEmptyListNum vor isEmpty ausgeführt. Damit ist es möglich, selbst ein leeres Array abzufangen und mit einem neuen Wert zu belegen.
