[JW Lua] TS and KS as strings example

[Charles O. Lawrence]

Thanks Jan.  Your reply had been pushed way down in my inbox, so I just now
saw it.  Makes good sense.

measure is a pointer to an object (an FCMeasure taken from the collection
FCMeasures).
If you do   print(measure)  you see the pointer.
Now you assign this pointer to lastmeasure. It points to the identical
memory that measure uses.
Check this script:

local measure=finale.FCMeasure()
measure:Load(1)
local lastmeasure=measure
print(measure,lastmeasure)
print(measure:ClassName(),lastmeasure:ClassName())

Anyone,
In this code, why is it not necessary to declare lastmeasre as FCMeasure()?
 
local allmeasures = finale.FCMeasures()
allmeasures:LoadAll()
print ("Measure Count",allmeasures.Count)
 
local lastmeasure  --  = finale.FCMeasure  apparently it is not necessary to
declare this as FCMeasure() local TSString = finale.FCString() local
KSString = finale.FCString() for measure in each(allmeasures) do
    if measure.ItemNo > 1 then
        measure.TimeSignature:MakeString(TSString)
        measure.KeySignature:MakeString(KSString)
        print ("Current
Measure",measure.ItemNo,"TS",TSString.LuaString,"KS",KSString.LuaString,"Las
t Measure",lastmeasure.ItemNo)
        if not measure.TimeSignature:IsIdentical(lastmeasure.TimeSignature)
or not measure.KeySignature:IsIdentical(lastmeasure.KeySignature) then
            lastmeasure.Barline = finale.BARLINE_DOUBLE
            lastmeasure:Save()
        end
    end
    lastmeasure = measure
end
