Patent ID: 7363485

Claim:
A method for modifying a control method name in an interface between a basic programming system and an operating system to control enabling of a control method associated with the control method name, the method comprising: checking for a selected setting indicating that the control method name is to be modified; searching for the control method name to be modified based upon the selected setting; modifying the control method name so that the operating system will not recognize the control method name and will not enable the control method associated with the control method name, if the selected setting indicates that the control method name not be recognized; after the control method name is modified, updating only a checksum associated with the modified control method name, wherein updating only the checksum associated with the modified control method name includes: zeroing out the checksum associated with the modified control method name, summing bytes of the modified control method name to produce a sum, inverting bits in the sum to create an updated checksum, and associating the updated checksum with the modified control method name so that the modified control method name will be valid to the operating system.
