NAME
     choice - select and output choices.

SUMMARY
     Name	   choice

     Type	   data

     Inputs	   none

     Outputs	   choice

     Parameters	   choice
		   string

DESCRIPTION

     The choice module allows the selection and  output of choice parameter
     values.  The output  can  be  linked  to  choice  parameters of  other
     modules.  This allows a single choice  widget to control more than one
     choice  parameters.   It  can  also be used to  restrict  the range of
     choices available.  The  available choices  are  set by the choice_str
     parameter.  This should be set to the list of the choices delimited by
     colons.


OUTPUTS

     choice out (choice)
	  The selected choice.

PARAMETERS

      Choice (string)
	  A title bar for the choice widget.

      choice (choice)
	  The choice parameter

      choice str (string)
	  The list of available choices delimited by colons.

EXAMPLE

     The  example network choice.net  illustrates how the ucd choice module
     may be used to  simultaneously control the axis choice of 2 orthogonal
     slicer modules.  The choice str parameter is set and then hidden using
     the network editor.
