The Input command returns an XML function call which represents an Input element of a Worksheet or Document.

The generated XML may be used with the results of additional commands in the Layout Constructors package to create an entire Worksheet or Document in XML form. Such a representation of a Worksheet or Document may be inserted into the current document using the InsertContent command.

The argument to the Input command is the result of a call to the Textfield constructor.

The result of the Input command is suitable as an argument to the Group command, in the sense that an Execution Group  of a worksheet can contain an input region.

An input region, represented here by the result of a call to the Input command, can be used in two key ways. One way consists of containing a Textfield comprising paragraphs of text, plots, or tables. Another way consists of containing a Textfield comprising executable statements, and this can be accompanied in an execution group by the result of the Output constructor.
