.CHART SET BG SIZE:H

This subroutine sets the background height of the "current" chart spec.

Usage:

      PASS         <chart_height>             FIELD            SHARE? N
      GOSUB    0CD .CHART SET BG SIZE:H
      *        Check for error
      IF       0CD .CHART SET BG SIZE:H          NE

Description:

This suboutine sets the height of the chart area for the "current" chart spec. The <chart_height> value specifies the height of the chart in pixels.

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.
