+as described below.
+\indent{0}\newline\tab{2}{\em Description:}\indent{15}\tab{0}
+{\em Record(a:A,b:B)} is used to create the class of pairs of objects made
+up of a value of type {\em A} selected by the symbol {\em a} and
+a value of type {\em B} selected by the symbol {\em b}.
+In general, the {\em Record} constructor can take any number of arguments and thus can 
+be used to create aggregates of 
+heterogeneous components of arbitrary size selectable by name.
+{\em Record} is a primitive domain of \Language{} which cannot be
+defined in the \Language{} language.
