find the palette highilghted?
That looks like the Data Queue PtByPt VI to me. Signal Processing->Point By Point->Other Functions PtByPt
Signal Processing > Point by Point > Data Queue
Tim beat me. And I forgot to write the "Other Functions" palette in there.
And rest assured: you can forget about that function once you passed CLAD!
You don't need to know it for CLD or CLA (or when programming). Go figure...
CLAD: Testing an engineers ability to memorize useless LabVIEW facts.
Good luck on the test!
