Abstract Several devices with two input lines and one output line are introduced. These devices are viewed as transformations which operate on pairs of (ALGOL-like) languages. Among the results proved are the following: (i) a pair consisting of a language and a regular set is transformed into a language; (ii) let (V, W) be a pair consisting of a language and a regular set. Then the set of those words $\textit{w}1,$ for which there exists a word $\textit{w}2$ in $\textit{V}$ so that $(\textit{w}1,$ $\textit{w}2)$ is mapped into $\textit{W},$ is a language.
