Description:

This suboutine sets the width and height of the chart area for the "current" chart spec. The <chart_width> and <chart_height> values specify the size of the chart in pixels.

The <chart_width> parameter is optional. If specified, it must be an unsigned numeric integer value between 0 and 99999. If the <chart_width> parameter is not passed or if the value passed is blank, then any previously specified value for <chart_width> is cleared and the default <chart_width> specified in the system parameters file is used.

The <chart_height> parameter is optional. If specified, it must be an unsigned numeric integer value between 0 and 99999. If the <chart_height> parameter is not passed or if the value passed is blank, then any previously specified value for <chart_height> is cleared and the default <chart_height> specified in the system parameters file is used.

This subroutine sets a result value in the corresponding results Token field.
