True. And it doesn't follow that it therefore makes sense to ignore
microseconds because of the other. I don't know the source of your
objection nor where you perceive seconds or minutes being thrown away, so I
cannot address further.

That's cute and I look forward to writing such a note a few/several
years
from now.

It's all relative. Microseconds may not matter in your business;
heaven
knows most System i are not exposed to high transaction volumes per
unit
of
time.

If, however, you design your applications to be used by several
thousand
users concurrently, those microseconds shall add up. It will matter.
It
does matter. Of course you have the option of never applying for a
job at
a
place that does that sort of business.

A little off-topic...

Some years ago Tracy Kidder wrote a wonderful book, "The Soul of a
New
Machine", regarding the efforts of Data General's computer engineers
in
building of their first minicomputers. In that chronicle, of of the
engineers charged with writing the computer's microcode got tired of
working
with oscilloscopes and nanoseconds and, I quote,

*"He went away from the basement and left this note on his terminal:
"I'm
going to a commune in Vermont and will deal with no unit of time
shorter
than a season." "*


Dieter, believe me, I really understand and share your sentiments...

I use a balance of RLA and SQL. Usually use RLA by default and
only go
to
SQL when it is a better fit (i.e. dynamic sorts, searches,
ranges,
etc).
We
are actively moving our web development (i.e. OpenRPGUI.com)
from
our
V5R3
server to our V6R1 server so I am planning on jumping into free
form
embedded SQL, and on that note...

Are there any well documented (i.e. articles) out there that
show
how a
CRUD
application would use embedded SQL for all file access? I ask
not
because
I
am new to SQL, but because I am not yet convinced of how it's
usage
is
being
described by some in this thread.

I must say that Alan's comments about lessening the compile
burden
is
something I hadn't considered to a great extent until I started
thinking
about it. Certainly better that wrapping file access with
*SRVPGM's
where
the whole record is being passed in/out without applying any
sort
of
business logic. I think this also comes down to having a good
change
management solution that does a lot of the work for you (as it
should).
