ABSTRACT:
A method for executing an iterative search for a desired record (111) in an ordered list of records (102) residing on a relatively slow background memory (214) includes a number of steps for copying the keys at relevant positions (112,114,116) into a relatively fast foreground memory (206). The method according to the invention retains a selection (230) among those keys in the foreground memory (206) for speeding-up the searching of a next desired record.
