I have a subfile program for updating, creating, and displaying item information the user can select from to create, view or update detail. The subfile shows item number, description, etc from my main file (i'll call itemnum1)and a vendor item number from an auxiliary file (itemnum2). My question is the users want to be able to hit a function key and have the subfile change from item number sort, to item description sort, or vendor item sort. the subfile currently is read from itemnum1 keyed on item number. Is there a way to sort the subfile without having to have multiple logicals?
