Determines whether order fitting/clipping is interactive.
Set TRUE for interactive order fitting/clipping.
If FALSE, order fitting/clipping proceeds automatically. When automatic fitting is engaged there are two parameters which may be adjusted to optimise the performance of the program. These are: TUNE_CLPMXDEV, which defines the clipping point, and TUNE_CLPBY, which is the number of points to clip in each iteration.
The default value is TRUE.
