Encountering this issue, I'm having a feeling of deja vu, so this might have been discussed before. But I can't find anything.
I found that a sequencer variable assigned to a waveform doesn't seem to know its current size. The pvCount() function always returns the value of NELM (or the array size of the sequencer variable, if smaller), not NORD. Is there some way to obtain the current size of the waveform that I missed? I'm not too keen on creating a separate variable assigned to the NORD field because there's no guarantee that the two variables will be in sync.Isn't https://epics-sequencer.sourceforge.io/sequencer-2-2/Tutorial.html#process-variable-element-count what you're asking for?
