There's one advantage to varying-length, even with full-length allocated value - reduced use of trimming in RPGLE. No advantage in RPG III, of course. ;-)

See my other post for more, and more, and more!!

After having read up, I have a couple of questions. If you don't care about space saving, can't you just code the maximum and allocated length as the same?

Yes, but what would be the point? That would effectively be a fixed- length field with an additional 2-byte length prefix. Might make it easier to determine actual length of the content but that's all.

How is space saved? I mean, if the allocated length is 0 and all the rows are in the overflow space, where is this space?

In an internal area associated with the file.
