In section 6.2, in the second paragraph of p. 335 (image below) of "Probability and statistical inference 7e" by Hogg and Tanis states:
perhaps it is known that $f(x;\Theta)=(1/\Theta)e^{x/\Theta}$
where $x$ is data and $\Theta$ is a parameter.
What does "$;$" mean in this context, as opposed to "$,$" or "$|$", all three are used in different ways in the same textbook ("," and ";" are used on the same page, $|$ in the standard statement of Bayes' Theorem)?
I think I understand "$,$" and "$|$" and I read $f(x,\Theta)$ as "function of data and parameters" and $f(x|\Theta)$ as "function of the data given parameters".
Here is a scan of the page for more context:
