1. A method for enabling receipt and storage of data by a movable barrier operator from a plurality of transmitter devices, each transmitter device maintaining a transmitter code and a unique serial number, each transmitter device having specific operational features, the method comprising:

  • designating a number of records in a memory array maintained by the operator;

    sub-dividing said records into at least two groups, wherein each group is associated with the transmitter devices having the same operational features;

    associating a predetermined number of binary bits with each of said records;

    designating by the operator one of said bits as a validity bit, and some of the remaining said bits as transmitter bits;

    receiving a transmitter code from one of the transmitter devices by the operator;

    sequentially comparing said transmitter bits of each said record with said transmitter code;

    determining whether said transmitter bits of one of said records matches said transmitter code, wherein if a match occurs at said determining step, said validity bit associated with said record is set as usable and said transmitter serial number is associated with said record.
