How to retrieve the number of waves from a srrWave object?

Not sure if there is a nicer way, but a naive approach would be to recursively dive into the family (of families, of ...) until you reach the waves, and sum up the numbers on return, as this would count the actual waves, independent on how the sweeps look like, e.g. like this:

procedure( count_waves_in_fam(wave)
  let( (cnt)
    cond(
      ( drIsWaveform(wave)
        ; a single wave
        1
      )
      ( famIsFamily(wave)
        ; call self with all family members
        ; sum up the returned count
        cnt = 0
        foreach(sv famGetSweepValues(wave)
          cnt = cnt + count_waves_in_fam( famValue(wave sv) )
        )
        cnt
      )
      ( t
        error("count_waves_in_fam: cannot handle %L\n" wave)
      )
    ); cond
  ); let
)

IF the number of waves is actutually not what you finally want, but to open subwindows for each wave, then you might add the opening part inside the 'drIsWaveform(wave)' condition, and replace the foreach with 'famMap('count_waves_in_fam wave)', which should be at least more efficient. However, if you want to pass values up (like the count here) or down (e.g. the current sweep values), then you have to iterate yourself.

Hi, 

Thanks for your reply. I haven't had the chance to tinker with this in the past days but I'll give it a go and report the outcome in the forum.
