RE: Subfiles was RE: Chalk one up for "The Cycle"

I guess they love the subfile so much that it's hard for them to leave,
lol.

Yep - the subfile had a position to field, but the user "preferred" to
use
page-up/page-down instead.

Hard to believe, maybe not. Do you have them enter a Search field this
would start the subfile at a later point.?

If the sub-file is a load-all sub-file it will happen BEFORE the first
page
is displayed.
As far as the "growing" sub-file, the problem of loading data into the
screen by hitting the page-up 500 or more times HAS happened a couple

of

times (believe it or not)

Yes, but probably not the way you're implying. Assuming the subfile

gets

20 lines on a screen the user will have to hit page down 500 times

(FIVE

HUNDRED) before that blows up. Assuming a more realistic 10-15

you're

in

750 to 1000 page downs. I have NEVER seen a case where a properly
designed screen/lookup/whatever requires the user to hit pagedown

500

times. The only thing I can see even coming close is a notes-display
screen, and even there, segment the notes somehow, by month? Year?
Century?

There ARE subfiles that will NEVER be more than 2 - 3 pages long

(List

of
account types that are defined as
d Accttype s 2 0

however, saying that, I've had to rectify subfile programs that will
NEVER
be more than 2 - 3 pages long and then die when they attempt to

write

the
10,000 record to the sub-file. As this program is in PRODUCTION this
problem needs to be rectified IMMEDIATELY, and believe me I've come
across
quite a few of these. It turns out that the original programmer was
either
NOT thinking, or was just taking the easy way out.
All I'm saying is, when creating a subfile, look at the length of

what

the
major key to that subfile is. If theirs a CHANCE that there are

10,000

or
more combinations within that key, bite the bullet and write a page

at

a

time subfile.

Last night whilst sipping my Manhattan on my deck (I find mint

slightest.

But, on the subject of subfiles , I still find that a lot people,
even for the simplest of subfiles want to put in code to control

the

scrolling, and want to build it page at a time even though they

know

it will NEVER be more than 2-3 pages long. Happily, for me, I have
not had to build a subfile in years that cannot be built all in

one

go and with the system handling everything, though I have had to
maintain a few of the others and what a pain it is. The standard

for

my current shop is that if the subfile is over 999 lines long the
program will crash, that is the standard I didn't write it, so,

for

one of the few times, on the programs I have changed I go against
the standard and don't allow the program to crash, hey maybe I am
one of those Rogue(or is it Rouge) Programmers that people are
talking about. :-)

Onderwerp: Re: Chalk one up for "The Cycle"


Last night, while sipping a mint julep on my deck, I got to

thinking

about the "non-cycle is more logical, intuitive." I have to agree

with

the statement, though I occasionally write cycle programs in ILE

RPG

(even with subprocedures - how sick is that?).


But, then, I remembered subfile programs. Though I write subfile
programs, no one has (yet) been able to convince me that subfiles

are

"easy and intuitive" to understand. On the other hand I wrote

subfile

programs on the /36. Since the /36 doesn't have the built-in
(cycle-like?) subfile stuff, everything (and I mean everything)

had

to

be coded in the routines.


As much of a pain as subfiles are to program (or maybe it's just

me),

I

haven't heard (and don't expect to hear) anyone wanting to code

subfiles

outside the built in system logic and handling. I no longer write
subfiles "manually;" that would be pretty masochistic.
