This code exposes another common feature of HyperTalk: that a property might have several names and operators. In this case the codice_20 command, and the associated codice_21, act by setting the value of the container's codice_22 property. Thus codice_23 is exactly equivalent to codice_24. A similar example was the codice_25 command that stopped visual updating, which was a short form for codice_26, where codice_27 is a property of HyperCard itself—also a container. Many examples of this sort of syntactic sugar were found in HyperTalk, in order to simplify the syntax and improve readability of common code.
