Simple List processing.

As with image processing there is a range of commands which allow simple operations to be performed on the contents of lists. With lists commands act on either the whole list or just a specified column, as appropriate.

For example, if ADDC is used when in list mode, it will add a constant to a specified column within the current list. This includes the SMOOTH command which, in list mode, convolves the column with either a tophat or gaussian filter.

Other commands available are:
