 $\begin{array}{lcl} \textbf{RECORD}~~~~ C &::& e\in E\\ && f \in F \end{array}$
 $\begin{array}{l} \textbf{SETS}~~ C\\ \textbf{CONSTANTS}~~ e,~ f\\ \textbf{AXIOMS}\\ ~~~~\begin{array}{l} e \in C \tfun E\\ f \in C \tfun F\\ \end{array} \end{array}$
Now, given an element $c\in C$ representing a record structure, we write $e(c)$ for the e component of c and $f(c)$ for the f component of c.
