We have just upgraded to AREV 2.12 from 1.16. For some reason when an RLIST statment is executed on a date field it will only use indexing if an EQ or=is used. If a from to, or between statement is used it will not use indexing. All date fields are right justified. Anybody have any ideas.
Try adding in the CASEINSENS keyword before the WITH field
SELECT FILE WITH CASEINSENS DATE BETWEEN '12/01/97' AND '12/31/97'
