Im using a pointer as input for a FB and for convenience I like to use 'referenced' variable internally.

I use this setup in methods which works because internal variables are instantiated for each call. In a FB these variables are instantiated and initiated for the first call only. Is there a pragma/attribute available that changes this behaviour to mirror a 'method'-call?
