ReDim is used to re-dimension an array. It is particular useful when you are likely to encounter an variable length array (different length each time the code executes). Normally when the array is re-dimensioned the previous values are destroyed because you normally want to enter new values into the array. Some flavors of basic allow to use ReDim Preserve to preserve the array's original value - you may want to try this to see if works. A common use is Dim MyArray() as type ReDim MyArry(1 to x), x will be supplied by the procedure. Often there are little subtleties that can drive you crazy when program, the compiler/interpreter is very fussy that you follow all the grammar and syntax rules for the langauge. -- Jay Lozier jsloz...@gmail.com -- For unsubscribe instructions e-mail to: users+h...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
