make a subVI do something on first call

[Fibo]

Hello,

I have a SubVI I made and I want it to do one thing the first time it's called and then as long as the program is running it should do another thing.  Right now I have a  "First Call" function wired to it, and that passes it a tru the first time my SubVI is ecounterd and a flase every other time... this works... but I was wondering if there is a way to do this from within the subVI itself?

Thanks!

Why don't you place the "first call?" primitive inside the subVI?

because if i do that, the first call would be true every time the Subvi is run.... wouldn't it? let me try this... i didn't even bother trying cause i figured the first call thing would run every time the vi is run.... i'll be back

You are absolutely right! I just thought... well... you know.
