Hi, 1.- Use extensively the "read-only" "repeat for each..." loop structure. 2.- Use extensively the array vars instead of "item-lines" tables vars to store the datas you are searching on, sorting,... 3.- Use B-Tree alike data storage structures if the datas you have to parse at once exceed 500 ko. 4.- Run your app under Linux (extensively tested as two time faster than both Windows or MacOSX). -- Cordialement, Pierre Sahores Inspection académique de Seine-Saint-Denis.
