public class Firstmark
extends Firstmarks

This class provides an implementation for the primitive \firstmark.

The Primitive \firstmark

The primitive \firstmark expands to the first mark on the current page. If no mark has been encountered on the current page then it expands to the last mark on the previous page. If no mark has been placed ever then the primitive expands to the empty token list.

See the documentation of the primitive \mark for further explanation of marks.

Syntax

The formal description of this primitive is the following:

    ⟨firstmark⟩
      → \firstmark
