[founditems] is infact a loop which automatically steps through all found records. Everythingbetween [founditems] and [/founditems] is executed record for record. Youcan use [showif]'s there to define conditions for various actions. For eachrun through [founditems] you can use data of the current record ifnecessary.If you do not need individual data of the current record but rather changeall or a selection of records by given criteria, a search is not necessary.Use [replace], which is actually query and replace in one command.--btw - to change fields within a [founditems] loop you have to use [replace]either. Since [replace] containes a search this is (in my opinion) wastedtime - I never understood why I have to do execute a new query for a alreadyloaded record...
