摘要：
A method, apparatus, and computer-readable medium for storing variables in a non-volatile computer memory are provided. The computer-readable medium has a data structure stored thereon that includes a first data field for storing a variable record including a header and variable information. The data structure also includes a second data field for storing a GUID for the variable. The variable record may comprise a full record or a data only record. A full record contains all of the identifying information for the record and the variable value. A data only record includes only an updated value for the variable. When a request is received to retrieve the variable value, the data structure is searched to locate the most recently created record for the variable. The value stored in this record is then returned in response to the request. Periodically, a garbage collection process may be performed to reduce the records stored for each variable to a single full record.
