The REC menu

A second collection ( f2) consists of packaged demonstrations, written in the programming language REC , many of which run through a series of steps. Their operation is launched by the key f5; the programs can be edited with the help of f3 and executed by f4 by a user who knows or can deduce the REC language, but this is not intended to be necessary to enjoy the demonstrations.
