NAME
     write irreg - write an ascii version of an irregular field in the
         "LBL" field file format.

SUMMARY
     Name          write irreg

     Type          render

     Inputs        field irregular

     Parameters	   filename
	

DESCRIPTION

     The write irreg module will write an ASCII representation of an
     input irregular field to a file.  The file format is the "LBL"
     irregular field file format, and is readable by the "read irreg"
     input module.

     This module is useful for looking at irregular fields, for example,
     after some processing step in a data flow network.

INPUTS

     field (any type, size, dimensionality) irregular

PARAMETERS

     filename - a browser is supplied to let the user specify the 
         filename to which the ascii representation will be written.

EXAMPLE

1.  The first example shows a network in which an irregular field
	is read in.  Next, a filtering operation is performed
	(thresh), then the converted field is written back out to
	a file.

LIMITATIONS
     The data values in the field are written out in floating point format.
     The input data field must be in floating point format.
