I noticed when creating Record Map's within Ensemble that it is creating a Persistent cache table as it translates the file and puts it into the Record Map data structure.

I was wondering if there was a way to add a column to the cache table that is Hidden from the record map, but is a calculated date value on when that record was inserted?

I have a %GlobalBinaryStream object that I'm trying to save as a local file after being received through a SOAP Web Service.

To do this, I created a %Stream.FileBinary object and wanted to set where the stream copied to this object would be saved by using either the DefaultStreamDir() ClassMethod or the NewFileName() ClassMethod. However, the documentation isn't very helpful on how to use these ClassMethods.

Right now, I have the below code:

Hi all,

The last time I used CSP was back in 2008, so I am very rusty on it.
This question might have been asked many times, and the answer probably is that it is a matter of preference.

Are there scenarios to which CSP pages is easier/better to use than classes extending from %CSP.Page?
I want to build a little thing and don't want to start at the wrong end.
Doing an API-based, heavy client-side framework is not a requirement, and I would prefer not to do it that way.

Some of the criteria

Technical surprises using VECTORs
>>> UPDATED

Building my tech. example provided me with a bunch of findings htt I want to share.
The first vectors I touched appeared with text analysis and more than 200 dimensions.
I have to confess that I feel well with Einstein's 4 dimensional world.
7 to 15 dimensions populating the String Theory are somewhat across the border.
But 200 and more is definitely far beyond my mathematical horizon.

We are creating a package (written in Caché Object Script) that will provide access to an external DB (MySQL). Because applications that use our package will be run from machines with various, potentially unexpected, operating systems, we’d like to establish a connection to the external DB without using DSNs (we’ve heard that setting up DSNs on certain non-Windows machines can be cumbersome and problematic).

Here are a few examples of conversions and operations you might need, along with links to documentation where you can learn more.

At the time I wrote this, Eastern Daylight Time was in effect for my Caché system.

How Caché keeps the time and date

Caché has a simple time format, with a longer range of recognized dates compared to some other technologies.

The current time is maintained in a special variable $HOROLOG ($H):

Hi all.

I have been using a command pipe to open/run UNIX scripts for months without issue. We recently installed the 2016 Caché Upgrade and now I'm getting the following error when opening the pipe:

<PROTECT> *OPEN[Q](|CPIPE|)

I assume some security or permission setting is to blame, but I'm not sure exactly what. Here's the snippet of code...

s cpipename="|CPIPE|"
s filepath="/path/script"
​o cpipename:(filepath:"R"):10

Any feedback would be greatly appreciated!

Earlier this year I announced availability of a VS Code extension for coding in ObjectScript, Embedded Python or SQL using the notebook paradigm popularized by Jupyter. Today I published a maintenance release to correct a "getting started" problem.

Here's a video of the installation steps from the extension's README:

Hello,

Is there a single ObjectScript operator or method to concatenate two %DynamicArrays?

I'm looking for something that will do the following:

set arr1 = [ 1, 2, 3 ]
set arr2 = [ 4, 5, 6 ]
set arrcombined = arr1.%Concatenate(arr2)

or

set arrcombined arr1_arr2

With end result:

zw arrcombined
arr1=[1,2,3,4,5,6]  ; <DYNAMIC ARRAY>

I can iterate and %Pop over the 2nd array and %Push each popped entry to the 1st array, but I was looking for something more succinct.

Thanks in advance.

Let's say I have two classes: A and B. They share no common parent except %SystemBase. But these classes have some properties with the same name (type may be the same or not):

Class A {

Property data As C;

Property data2;

}
Class B {

Property data As D;

Property data3;

}

I need to automatically convert object of class A into object of class B. I'm planing to write a class generator that generates a separate class that converts A to B. It would work like this:

Hi All,

Just wondering if anyone had got this working.

In the documentation it says to set the username and password properties of the connection object but these properties don't exist and without authentication I can't connect to the MQ queue.

Any help would be greatly appreciated,

I'm trying to write an ObjectScript function that sorts version numbers to help learn ObjectScript. This is all I can think of after staring at VS Code for a while, but I don't know where to go with it. Can someone please help out with a tip? The goal is to take something like ["1.4.5", "0.5.3", "6.3.2", "1.2.4"] and turn it into ["0.5.3", "1.2.4", "1.4.5", "6.3.2"]
