Class Closein

      extended byde.dante.extex.interpreter.primitives.file.Closein
All Implemented Interfaces:
Code, Localizable, java.io.Serializable
public class Closein
extends AbstractCode

This class provides an implementation for the primitive \closein.

The Primitive \closein

The primitive takes one expanded integer argument. This argument denotes a read register which will be closed if it is currently assigned to a file – with \openin. If the input file assigned to the given number has not been opened or has been closed before then this primitive simply does nothing.

Syntax

The formal description of this primitive is the following: 
    ⟨closein⟩
       → \closein  ⟨infile name⟩

Examples

    \closein5  
    \closein\count120
