[JW Lua] Deleting all parts

[Jan Angermüller]

Jari,

thanks for your answer!

Sorry to ask again, but what does it mean regarding my proposed "Delete 
parts" script?
Is it allowed to call it? I.e. although the Finale PDK doesn't offer a 
"Delete parts" function the script still deletes all the necessary data 
without causing problems.
Or is it "dangerous" to the Finale data?
Or is it unknown if it's ok or not? (i.e. better not use it...)

Best,
Jan
