Don't be confident in this, it fails in at least 2 situations:
• compiled if the array is local
• in a host/component context if the variable belongs to "the other"
There is also "API Get Array Item Pointer" from APIpack plugin, but it does not
work in component/host context too.
More generally, each time I use "Get pointer" (or "RESOLVE POINTER", similar),
I feel like being using the "last chance solution". Better to ignore they
exist. I recently found that in my own old code:
for($i;1;10)
$var:=Get pointer("myVar"+string($i))
end for
Shame on me, that's an array.
I think there is a gap in 4D langage, I'd like 4D to fill it:

Re: Exodus utilities live?
Hi David, Thanks for asking about my old components - good timing. All my components (including ones never for sale) are v16 ready, and I've been looking to upload them as open source once I figured out the right repository. Most have been kept up to date & debugged, although Freedom of Choice (my displayList replacement) is long in the tooth and needs to be updated to use list boxes. Any thoughts on the right place to have these so the 4D community can best access them. Looking at GitHub but haven't quite figured it out yet - seems better for raw code as text rather than 4D packages Bob Finnerty On Thu, Jun 1, 2017 at 2:19 PM, David Eddy wrote: > Dr Finnerty - > > I happily bought & used your Exodus utilities back with 4D v2004.

Re: Macro anyone?
Hi Bob,
Thanks to the (absurd) federal EHR requirements, my old Patient Manager EHR
has become a dinosaur, but I've been slowly reworking it from 2004 to v16,
as I still need some of its functionality (I working for CHI as a specialty
inpatient hospitalist).
Good to see your still in the 4D world as well

Re: v13+ What table does a set belong to?
Jeremy -
Thanks - and it looks like a possible solution,
The rest of this comment is more aimed at the forum post of Olivier (copied
below) - but
This seems like a LOT of work, much more so that a single call to the server.
and it seems a lot of overhead for every set 'math' operation, for all sets
involved.
something like (calling your routine 'Test_set'):
if (Test_set(Setname1))
if (Test_set(Setname2))
if (Test_set(Setname3))
// now all the sets are known valid
union(Setname1;Setname2;Setname3)
end if
end if
end if
Olivier's forum post (on my feature request)
During a previous summit pre class, I explain and demonstrate how it's
dangerous to have the same name for sets of different tables. That's an usual
explanation of unnecessary exchanges between client and server.
So it's a good
practice to put the name of the table inside the name of the set. Thanks to
this rules you prevent a lot of viscosity and "eliminate issues with
(accidentally) trying to do set manipulations on sets from different tables".
This feature request need a call to the server to read the parent table. I
prefer avoid unnecessary exchanges and read a part of the set name. The read is
local.

Printing ListBox that is longer than a single page
I want to print a form that contains a single listbox. How do I make the list box print beyond the first page? Works great if the list fits on a single page, but only prints the first page if it is longer. I have the listbox fully inside the detail area and have tried using PRINT SELECTION and Print Form. There is a text variable that needs to print as well above the listbox. Looks like I need to use Print Object but need an example of how/where to use it.

Re: Printing ListBox that is longer than a single page
OK. I got it working. Perhaps this might be of help to someone else in the future. My list box is an array based list box which is being populated at print time. The listbox on load form event uses LISTBOX INSERT COLUMN and a few object commands to build the listbox with previously populated arrays. I got it to work with the following… PRINT SETTINGS $printed:=0 If (ok=1) OPEN PRINTING JOB If (ok=1) FORM LOAD([_Constants];"HouseCallsFirstNames.Print") Repeat $end:=Print object(*;"HCFirstNameReport") If (Not($end)) LISTBOX GET PRINT INFORMATION(*;"HCFirstNameReport";lk last printed row number;$printed) If ($printed=42) PAGE BREAK End if End if Until ($end) End if CLOSE PRINTING JOB End if Note that for this to work the loading of the listbox has to be in the listbox on load event, not the forms on load event.

Re: v16 Component Compiler error
Bob, I'm betting that one of the components has the offending culprit in it - either a variable name or method name. And the method may be invisible which makes it even more challenging to identify.

Custom comments: Lots of tips, more wanted!
I'm looking at custom constants again and have put together some thoughts. I wanted to post them here for the sake of the archives, and to solicit expansions, corrections, tips and the like. If you've got anything to add, please contribute! Here goes: * Right now, not that many people are using thread-safe processes in V16, but that will change. One of the limits of preemptive mode is that you cannot use IP variables. For a lot of existing 4D systems, IP variables have been used instead of custom constants. So, going forward, making custom constants easier to love is a Very Good Thing. * Custom constants are great, but they can be a bit of a pain...so they aren't used as universally as they could be. (Should be?) * One of the pains is that you have to reopen the database to see custom constant modifications. *This makes sense.* Constants are values that cannot change at runtime, so 4D loads them once at startup before our code. *But this is a pain.* If you agree, please vote in favor of this feature request: Please add a 'Reload constants' command http://forums.4d.fr/Post/EN/19514761/1/19514762 * 4D supports custom constants of the simple types Longint, Real, and String. * Boolean would be a big help, please vote in favor of this idea here: Please add support for custom constants of type Boolean http://forums.4d.fr/Post/EN/19514786/1/19514787 * Constants are better than static variables because no lookup, initialization, etc. needs to be done. The value is set once and that's it. In a compiled application, the value of the constant is baked right into the code. So, you can throw away a constants file from a deployed component or application. * Duplicate constants are a Very Bad Thing. With that in mind: -- Remove constants from compiled components. Helpful. -- Consider a naming starting constants like K_ or your initials, a module prefix, or a program-specific prefix. * 4D Pop works fine, but then the constants definition is not in your code. Alternatively, Jim Dorrance has posted some constants management code here and Cannon Smith includes custom constants code in some of his (free) modules. I'm using Cannon's code at the moment and it has made my life a *lot* better. No criticism of 4D Pop (none! I'm grateful), but I find it easier (a lot easier) to have everything in the code. * Sigh. Constant names/labels are limited to 31 characters. Why? No idea. If you agree that this limit is too low, please vote in favor of this request: Raise the 31 character name limit on methods http://forums.4d.fr/Post/EN/18946884/1/18946885 It's on 4 stars with 56 votes. Four more and it hits 60 votes! P.S. If you don't think 31 characters is too low a limit for names, you are a monster. Just saying. What have I missed? Been misleading about? Been wrong about?

Since I've been using c-obj more and more for parameter passing and just general data handling in memory I've started using constants more than before for object keys exactly because of the need for keys to be exact.

You've been mentioning this for some time and I eventually came around to
your point of view. 100% agreed.

I'm not sure what it entails on a technical level for 4D but, hopefully,
it's an easy one.

Huh, interesting idea. Do you mid submitting that as a feature request and
see what we get back? I think what I'd ask for is along the lines of a
build option "Delete constants from built application/component". Something
like that. What do you think? Either way, please put in a feature request
for what you like and post a notice here so that those of us interested in
the subject can vote.

Agreed. I've thought so since custom constants were first available in 4D
6.5. Holding breath.I think that would mean storing them in the
struture, which has some downsides and doesn't seem to be the way 4D is
heading. I'm not sure how best they could integrate them natively in
design, but it sure would be nicer. Maybe some kind of define statement?
Define(Theme;Label;Value) // Value can be Long, String, Real, or Boolean
Define("Error Constants";"Error level is informational";1)
Define("Error Constants";"Error level is warning";2)
Define("Error Constants";"Error level is error";3)
Define("Error Constants";"Error level is critical";4)
Define("Error Constants";"Error level is fatal";5)
Thoughts?
