Well yes, you do have to add the [smoke] entries in the aircraft.cfg file...Just use the normal XML to C sequence:int number;execute_calculator_code("number (>K:SMOKE_ON)", NULL, NULL, NULL);

Thanks Bill - them's exactly the lines I was thinking of working along.-Dai

For qustions to clarify the point:

1. Are you refusing to share your secrets?
2. Are you refusing reasonably?
3. Is he refusing to share his secrets?
4. Is he refusing unreasonably?

I am new to this forum but I know if i had knowledge that can help someone ,I certainly would give help.So this thing with giving up your secrets???? Give me a break! It reminds me of when you were a child in school ,"na na na na i got a secret.........!" :( With time people can figure out your "secrets" Keep in mind this is just an observation! Just reminds me of KIDS bragging about little secrets. Sheeesh!! :(
