Hello Gary,
On 3-24-04 a post by Graham did an excellent
job providing pertinent information on the use of the keyword
CUM. I don't think that a more robust elaboration on the typical use of
some of the keywords in the users guide is unreasonable. After all
they are keywords and it's not like you can go to the bookstore for
a reference manual on AFL, as you can on a foreign language.
Everyone usually has some preconceived notions about what to expect when
they start working with a new program. I expected to find a section
on creating or building a system. Well it's in the user's guide
but not really as a section such as is devoted to " A Beginner's Charting
Guide", which I personally don't really care much about right now. The
optimum use of "function" and "procedure" as explained in the user's guide
doesn't exactly jump right out at me either. Why and when and how I would use it
to advantage just aren't in any context that I can use.
I'm not here to criticize the user's guide and
I'm not seeking advice on the mentioned topics, they are just examples that
come to mind of questions that I have had. I really don't know what could
be expected out of a person trying to do anything in AFL if they had no prior
programming experience. But if you suggest that this person pour over code
to learn AFL that did not contain concise explanation then it could be like
picking up a foreign newspaper and not knowing their alphabet. If you learned in
this manner then you ought to be commended for accomplishing so
much.
I'm not advocating for or against your effort
to"work up a to do list", and I'm not advocating less reading as has been
previously suggested. I'd just like to see more of something to read in
certain areas.
Regards,
Glen

Kevin,
I gotta offer some tough love here because I, along with everyone else on
this board, have been or currently are in the same situation you are.
If you've ever had the pleasure of learning a foreign language, you may
recall how much of a pain it was to learn conjugation of verbs, learning
vocab, and understanding concepts of grammar. If you were even more
fortunate to have gone to a foreign country to apply your learnings, you
realized that what you learned in books was only scratching the surface.
Well Kevin, AFL is no different. You must go through the entire
help file that encompases AFL. You must read through every
function. You must read every line of code from every post on this
board.
Initially, you will only understand 1% of what you read. However,
after enough iterations, you will gradually get a grasp of the language, and
the inherent power that it offers.
I'm not programmer by trade, but if I could learn AFL then you can too. :

Kind Regards,

Yes, the AFL functions do have an
example, however, they are of little value to non-technical
folks such as myself and Yuki. Every time that I look up a
function, it has only the techie definition, and obviously, that is as it
should be.
However, when I click to go on line to see more
detailed information, there is usually no additional detail there to
see.
The help provided by this board has been enormously
helpful. However, non-techie newbys will be able to grasp it
much faster if we could see examples of practical use of these
functions when we click go online to see a more detailed description.
Below here I have pasted an earlier email from
a very frustrated Yuki.

easy -- so very bloody easy that it is *extremely*frustrating that I
could not come up with it myself. Perhaps thesethings are only
easy in retrospect -- at least I hope so. I neverreally thought
of myself as mentally challenged until I started usingthis
software. ^_^ I knew of this function, but a practical use
forit simply eluded me. This is true of any large number of
AFLfunctions. ^^_^^The AFL reference is simply not all that
much help for minds that arenot accustomed to programming, I
think. Here is what it says aboutthis
function:SYNTAX GetDatabaseName()RETURNS STRING
FUNCTION retrieves the name of the database - the last part
(folder) of the database path EXAMPLE SEE ALSO
And this was from the updated/extended version
online.Okay, it retrieves the name of the database. Whatever
would I everwant to use that capability for? ^^_^^ Now I
know, of course.My point here is that this function was included
into the AFLlanguage for a reason. The developer (TJ) had a
notion ofspecifically what this might be used for, and it turns out to
be veryhandy indeed for this situation that I have recently come
across. YetNO notion of any specific practical way that this function
might beused is included in the AFL language reference, at least none
that Ican find. There is some kind of thought bridge here that
programmerscan easily cross, and non-programmers (at least this
non-programmer)cannot.A specific example of practical usage
should be given for AFLfunctions in the reference, I think.
These examples should bewritten in NON-PROGRAMMING prose. ^_^ They
should be the antithesisof Linux MAN pages. They should take
little grasshoppers like me andlead them to discovering practical
usages for the function.I would be willing to help anyone that
would like to work on thistype of project. I'm afraid, though,
that my contribution would belimited to cleaning up the wording, and
making it clear. And also,if I can understand it, it's probably
a great filter for 'ready' or'not ready'.Yuki

Odd....in my
version of AFL function reference nearly every AFL function has an
example, many more than one, attached to
it.....

I asked a simple question and got a lot of answers that have nothing
to do with the question I asked. You don't know me, so how do you
know what I need. Does anybody know of a good book that comes close
to AFL? What's missing in the documentation is examples.
That's how you learned things in school - working through examples and
finally creating your own routines to solve new problems. That was
true for basic Addition math all the way through Differential
Equations.
Two salesmen in Best Buy kept telling me the print cartridges they
handed me would work in my printer today. I kept telling them no,
they won't work. They talked me into trying them.
Of course they didn't work......

You
might have a look at the simple program written by Bill Peters over at
ABtools.com it allows you to tell the program what you want in
English then it spits out the AFL equiv. It may give you a quick start
on AFL programming
