Vector Definition in Preprocessor

I was trying to define a vector as a variable

for which Flair seemed to accept and evaluate just fine.

However, when I tried to actually run it, I get the following error

Abort called from LFLPRP reason DEFINE 4TH FIELD IS NOT A COMMENT Run stopped!
STOP DEFINE 4TH FIELD IS NOT A COMMENT

I know the #define card with the vector definition is the problem because if I disable it, it runs like normal.

Is it possible to define vectors in with preprocessor variable?

Thank you @Dirk.A.Bartkoski for reporting the bug.
The FLUKA parser do not accept this syntax. We will try to fix that for the next release either from the flair side and/or fluka side
