01 · OVERVIEW

Overview

The function is used for selection markers, as demonstrated by MsSelect. The historical manual describes optional lMaiusc to restrict uppercase characters. It is a function despite its old queue classification, and not an authentication token. Current MsSelect documentation marks that class deprecated and recommends FWMarkBrowse. (Sources: refs. 1–2.)
