A method is described for inhibiting the use of illegally copied programs by requiring the use of an encoded card to enable the execution of a program. The method disclosed comprises the steps of (a) recording a pertinent portion of the program in scrambled format; (b) at run time, testing whether the scrambled portion is being referenced as the next instruction to be executed; and (c) if so, fetching the data and unscrambling it with the information on the encoded card.
