---++ Description:

This subroutine sets the title for the "current" chart. This subroutine only needs to be called if the chart is to have a title or if a previously set chart title is to be changed or removed.

*&lt;chart_title&gt;* is the text string which will be rendered as the chart title in a text box normally positioned at the top the chart area. The *&lt;chart_title&gt;* parameter is optional.
   * If a non-blank *&lt;chart_title&gt;* is passed, then a title is set for the "current" chart. If a title has been previously set, then that title is replaced.
   * If a *&lt;chart_title&gt;* is not passed or if a blank title is passed, then no title is set. If a title has been previously set, then that title is cleared along with all of the related chart title attributes.

*&lt;text_box_name&gt;* is the name of a previously initialized text box. The *&lt;text_box_name&gt;* parameter is optional.
   * If a *&lt;text_box_name&gt;* is passed, then the attributes of the specified text box are used as a prototype for the attributes of the *&lt;chart_title&gt;*. Two special keywords may be used in lieu of a *&lt;text_box_name&gt;*: "INITIALIZE" and "CURRENT" 
      * "INITIALIZE" indicates that the chart title is to be set and no special title attributes are to be set. Any previously set title attributes are to be cleared.
      * "CURRENT" indicates that the chart title is to be set and the attributes of the "current" text box are to be used as a prototype for the attributes of the *&lt;chart_title&gt;*.
   * If a *&lt;text_box_name&gt;* is not passed, then the following rules determine how the attributes of the chart title are set: 
      * If the chart title has been previously set, then the new chart title is set and any previously set attributes of the chart title are not changed.
      * If the chart title has not been previously set, then the attributes of the "current" text box will be used as a prototype for the attributes of the &lt;chart_title&gt; provided that the "current" text box has been explicitly initialized or is associated with another chart's title. If the "current" text box is not appropriate, then no attributes of the &lt;chart_title&gt; will be set in conjunction with setting the chart title.

If no attributes are set for a chart title, the title is rendered using certain default text attributes which are appropriate for a chart title. For example, the chart title will be be positioned at the top of the chart area, centered horizontally, and rendered using a larger, bold font.

The chart title text box become the "current" text box and subsequent calls to the various text subroutines may be made to further set/modify the text attributes of the chart title.
