My first Foxpro Advisor article referred to the work of Tom Lewinson who theorized that Rushmode builds a bitmap where each record matching the condition is represented by a 1 and the non matching records by a zero. This bitmap would have to be in physical record sequence. Any other sort order will make it impossible to just jump from record to record.
