RE: QSRLSAVF format SAVF0100

["Bob Cozzi" <cozzi@xxxxxxxxx>]

I understand that issue, it shifts everything up X bytes.
But the OVERLAY keyword can often resolve that issue, but why might you
comment-out a subfield in an API DS anyway? Certainly during testing this
may occur, but not during production. And anyway if you did, it may be
because you inserted too many fields or a duplicate. So you comment it out
and now, assuming from-to column notation, you have to adjust every single
subfield that follows it.
My philosophy on this is to only use length-notation and look at from-to
columns as nearly the same style coding as conditioning indicators EXCEPT in
the situation when you've /COPY'd the code from QSYSINC or elsewhere (that
is, from someone else's code base). Sure it would work, but do you really
want to do that?

Bob,

I don't think it is a very good idea to use length notation for an API data 
structure. The layout is not defined by the programmer, but by IBM, so you 
better have your positions right. Imagine using length notation and
commenting 
one line out.
