I know that I can write a conversion program to read in the old file, populate the new file, and get the desired outcome. But I was hoping my initial approach would work.
Before you trim out the trailing blanks, your variable length fields are stored in a secondary storage container that's part of your file object. Even though you update these variable length fields to a length of zero, all/some of this storage space in the secondary container is left for new variable length field values that will be added in future inserts, updates, and deletes. In addition, the usage of variable length fields add some additional overhead to each record to keep track of the location and length of variable length fields. Also, if your variable length field is 30 bytes or less, than DB2 may also ignore your Allocate setting.
