  if (lines[i].indexOf("Stem=") > 0)  // Already has stem direction specified
    continue;
  else {
    result = lines[i].match(/(\|Note.*Pos:)([n#bvx]?)0/) // 1. Note thru Pos 2. Accidental 3. Position 4. Shape 5. Ties 6. To end of line
if (result != null) {
  lines[i] += "|Opts:Stem=Up" }
   } }    // End main loop

If you have to transpose after running this, run Audit Note Stems and then rerun it.
