Hi Barbara, >>Within your program, a VARYING field has a fixed storage size (the maximum length of >>the data plus two bytes). If you do %SIZE on the field, you will always >>get the same result no matter what the current length is. Does this mean, that in RPG always the maximum length of the database field will be reserved, even if the database field is defined with VARLEN(xx) or ALLOCATE in SQL?

Within your program, a VARYING field has a fixed storage size (the maximum length of the data plus two bytes). If you do %SIZE on the field, you will always get the same result no matter what the current length is. -- This is the RPG programming on the AS400 / iSeries (RPG400-L) mailing list To post a message email: RPG400-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/rpg400-l or email: RPG400-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/rpg400-l.
