<h3>Description</h3>
<p>This project contains a definition of a module which allows
the user to select columns of data. The input data for this module is a table
</p>
<h3>Inputs</h3>
<p><b><i>Columns_In</i></b></p>
<p>
Data_Array that provides the columns to select from. This Data_Array can be provided by the Read_Column_File module.
</p>
<h3>Parameters</h3>
<p><b><i>labels</i></b></p>
<p>
String parameter which specifies the title of the column of data selected.
</p>
<p><b><i>selected</i></b></p>
<p>
Integer parameter that specifies which column of data has been selected.
</p>
<h3>Outputs</h3>
<p><b><i>Columns Out</i></b></p>
<p>
Integer output specifying the columns that the user has selected.
</p>
<h3>Utility Macros</h3>
<p>
The SelectColumnFunc functional macro uses the SelectColumnCore low-level module.  The SelectColumn user macro uses this functional macro and the SelectColumnUI user interface macro.  All of these macros use the SelectColumnParams parameter block to communicate parameters between themselves.
</p>
<h3>Example</h3>
<p>
One example application is provided with the SelectColumn project.  The SelectColumnApps example application reads in a data file and allows the user to select various columns.
</p>
