.CHART SET CNR R:TL

This subroutine sets the radius of the top left corner of the "current" chart spec.

Usage:

      PASS         <corner_tl>                FIELD            SHARE? N
      GOSUB    0CD .CHART SET CNR R:TL
      *        Check for error
      IF       0CD .CHART SET CNR R:TL        NE

Description:

This subroutine sets or resets the radius of the top left corner on a rounded edge. You must also set the corner style to Rounded via .CHART SET CNR STYLE for this subroutine to have any effect.

The parameter is optional. If specified, it must be an unsigned integer in the range 1-999. It represents the radius of the specified corner in pixels. A blank will be reset to the default value of 10 pixels.

You can also use .CHART SET CNR R:TR, .CHART SET CNR R:BL and .CHART SET CNR R:BR to set other corners, or .CHART SET CNR R to set them all at once.
