Controls the display and selection of waveforms. There can be up to eleven
waveforms displayed at one time, but only one waveform can be selected at a
time. The selected waveform is the waveform that was most recently turned on.
This command is equivalent to pressing a front-panel CH or MORE button.
<wfm> can be CH<x>, MATH<x>, or REF<x> except in extended-acquisition-
length and InstaVu modes where MATH<x> is not used.
