This is then translated to the relevant frequencies and passed to the selectfrequency function described above. Like the selectfrequency function this function may also copy data that is outside the band if some of the data in an input record is inside the specified band. If the input parameter is unset then no frequency selection is done. This is the default. This functions returns F if the selection could not be done.
Arguments bandname The frequency band to select.
See the example for the selecttime function.
