RE: Opinions Wanted: List API loop logic

[Scott Klement <klemscot@xxxxxxxxxxxx>]

John,

Thanks for the reply.

The "DataOffset" is a variable that I receive from the API itself.
There's no guarantee that the first entry will immediately follow the
header.  (In fact, it frequently doesn't, since there's an "Input Parm"
section, and some other sections)

Your idea of keeping track of the total offset from the start in an
integer field, rather than keeping track of the next pointer position as I
do, is interesting, though.  I'll have to think about that some more.

Thanks!
