Any gotchas using VARLEN fields?

["mlazarus@xxxxxxxx" <mlazarus@xxxxxxxx>]

 Is anyone using VARLEN fields in DDS?  We are thinking of implemeting it
in a few files that have some large, seldom used, text fields.

1)  Do the leading length bytes always have to be taken into consideration
or will an EVAL or MOVEx know where to put the data (similar to the VARYING
keyword)?

2)  Does the target length have to be set manually when updating the field
or will RPG set it properly?

3)  If the H spec and compile do not specify CVTOPT(*VARCHAR), will the
program bomb on a read, even if the VARLEN field is not referenced in the
pgm?

 A search seems to turn up little useful information (from a big picture
standpoint.)  Does anyone have a writeup, article, link, manual etc. they
can send?

 Thanks.
