    at least one store circuit for storing information relevant to tickets to be issued by the machine;

    means for supplying information to specify the syntax of operation of the ticket issuing machine dependent upon information entered into the machine through the keyboard;

    a printer for printing ticket information on a ticket in accordance with ticket information supplied to the printer by information supply means including the at least one store circuit and ticket information entered into said machine through said keyboard; and

    at least one selection circuit for receiving the information to specify the syntax of operation of the ticket issuing machine and for identifying, based upon the particular syntax, which of the different ticket issuing information corresponding to the different identification means entered into the machine upon depressing a single key of said keys including more than one different identification means is relevant to the particular syntax operation of the machine, whereby the appropriate ticket issuing information corresponding to the particular relevant identification means desired by an operator depressing said single key is automatically entered into the machine and the inappropriate ticket issuing information corresponding to the particular irrelevant identification means not desired by the operator is rejected and not entered into the machine without the operator having to depress an additional key prior to, simultaneously with, or subsequent to depressing said single key.
