refnum out: where to find it on the function/control palette?

[sunflower2772]

Refer pic. Refnum out looks like a dummy variable to paste to the shift register so the register would not be empty, am I right?

But I searched on the function/control palette, I can't find refnum out, where is it?

I don't know that there is an empty "file refnum out" constant, but it can be created in a couple of ways, the first being right clicking on a file function that creates a refnum and doing a "Create constant" another is clicking on an existing refnum wire, or in your case structure instance, the  terminal unconnected in this case and doing the same (essentially the same thing as the first), and a third is dropping a byte stream refnum control on the FP, going to diagram and right clicking it an "change to constant". All are a couple more keystrokes/mouse clicks from just pulling it from the pallete.
