Iteration End Number Use this field/slider to specify the number at which to end iterations. This option is available for cases that terminate prematurely, or which you want to run further. To Specify the Iteration End Number: Either type the desired value in the text field or move the slider to the right or to the left to specify a value. Tip: To change the scale of the slider, right-click on the slider and select Rescale Slider from the pop-up menu. Change the upper and/or lower boundaries in the window that appears, to rescale the slider and click OK.
