Tim,
I was not convinced that proves it. Internally, it could just keep track of the
largest value and return null for any values in between that are not assigned.
But I thought of a test that likely proves you are right:
C_COLLECTION($test)
$test:=New Collection
$test[MAXLONG-5]:=5
You'll be

Actually, it does create 247 empty elements (null to be
In the 4D case and in the cases below (plus PHP), I suspect a collection is
really just an "object" (hash table) with numeric keys instead of string keys.
For example, if I write
$collection := New collection()
$collection[247] := "fred"
I doubt that it creates 247 (indexes 0-246) empty
Anybody here remember Pick Basic? A record had many fields, each field could
have many values, and any value could have many sub values.
Like working with a cube where you can reference any point in the cube, and may
be of any type.
When used properly, the structure was marvelous. When abused,
Please. You mean like an array in almost any other language:
python:
x = ["fred", 2, {"test":4}]
javascript:
var x = ["fred", 2, {"test":4}];

In the full version download I see both 4D Internet Commands and 4D Pack in the
Plugins folder.
Also, 4D Internet Commands seems to be installed by default in the 4D
application. So you don't really have to install it at all if you want to use
the version that matches the 4D version you have.
Hi Bob,
After you install v16.x the 4DIC plugin should be in the installation folder.
For v16.3 check the following locations:
On Windows 32 bit, C:\Program Files (x86)\4D\4D v16.3\Plugins\
On Windows 64 bit, C:\Program Files\4D\4D v16.3\Plugins\
On Mac 32 bit, /Applications/4D v16.3/32-bit
Hi Bob,
Sorry, I don't know.

OK, like PHP arrays

Hi Jim,
I feel a bit silly, but I've just killed an hour looking for the v16
version of "4D Internet Commands".The v16 Conversion manual specifies
there are differences between v15 and v16, so I presume there is a v16
version out there, but I don't see it on the FTP site (mostly old stuff

I use
SET PRINT OPTION(Paper option;"A4")
to set the page size to A4.
But this doesn't seem to work.
If I view the document that was created, go to
Document->Page size
No page size is selected.
I choose A4 and the page size changes accordingly.
BTW if I go again to Document->Page size, it
Hi Kirk,
Thanks for diving into my subform problem

I have converted the parent form, with 23 programmatically build listboxes on
it that are show/hidden, into a parent form with 7 subforms with static
listboxes (columns created in design mode)
13 matches
