[JW Lua] Enharmonic Flip Bit

[Jan Angermüller]

Robert,

I have recently had a document that included seemingly "empty" 
FCNoteheadMods.
I.e. all options from the NoteheadMod dialog were set to the default value.

So I deleted it with nh:DeleteData(), because I thought it was an 
unnecessary/corrupt FCNoteheadMod.
This lead to a problem:
When you do the CreateRawDataDump and list the 11th value, it may 
include a "4", and 13th value may include a "13".

local nu=nh:CreateRawDataDump()
print(nu:GetItemAt(10).Int)

If this returns 4, then the "Enharmonic" bit is activated. Otherwise it 
returns 0.
If you delete the FCNoteheadMod in this case, the enharmonic flip 
disappears.
nu:GetItemAt(12).Int sometimes returns "13". I didn't find out what this is.

As Perfect Layout wants to delete corrupt/empty FCNoteheadMods by 
default, it's difficult to find out when looking at the score only:
If the enharmonic flip is only in a linked part and you load the 
FCNoteheadMod in the score, you won't recognize that there may be a flip 
in a part.
Or in other words: if you analyze the DataDump in the score, it looks 
like the FCNoteheadMod doesn't make sense, because all values are set to 
0 (except the 100 resize value).

My questions:
- Maybe you could add the GetEnharmonic() to FCNoteheadMod?
- Maybe you know what the 13 is?
- Do you know if there is a simple way to decide when looking at the 
FCNoteheadMod in the score whether this is a "false/empty" FCNoteheadMod 
or if this is actually an unlinked FCNoteheadMod?
According to my documentation there have been situations (maybe in 
corrupt documents?) where false/empty FCNoteheadMods should be deleted.
Until now I did when all values where set to the default values in the 
score. And I don't want to switch through all parts at that point, if 
possible.

Here is a test script for the attached document:
local reg=finale.FCMusicRegion()
reg:SetFullDocument()
local parts=finale.FCParts()
parts:LoadAll()
for p in each(parts) do
     p:SwitchTo()
     for e in eachentry(reg) do
         if e.NoteDetailFlag then
             local nhmods=e:CreateNoteheadMods()
             for nh in each(nhmods) do
                 local nu=nh:CreateRawDataDump()
                 if nu then
print(p.ID,e.Measure,e.MeasurePos,nu:GetItemAt(10).Int,nu:GetItemAt(12).Int)
                 end
             end
         end
     end
     p:SwitchBack()
end

Four notes have enharmonic flips and two also have the "13" value.
Three notes have the "4" in the linked part, one note has it in the score.
