First-class function^wiki

In computer science, a programming language is said to have first-class functions if it treats functions as first-class citizens. This means the language supports passing functions as arguments to other functions, returning them as the values from other functions, and assigning them to variables or storing them in data structures. Some programming language theorists require support for anonymous functions (function literals) as well. In languages with first-class functions, the names of functions do not have any special status; they are treated like ordinary variables with a function type.

[2, 3, 5, 7, 11, 13, 17].forEach(function(i) {
  console.log(i);
});

How to do something like this in Caché using COS?

Below are some exercises on this topic.

Hi, Community!

I have a process that I am trying to duplicate from SQL Integration Services (SSIS) into Ensemble so that the rest of my team can help support any issues that may happen.

This particular job creates multiple dictionary files, but for each one of the dictionary files it creates, it also creates a control file that tells the vendor what to process.

Hi All,

Am getting the following error while try communicate with one ensemble from another ensemble using SOAP Adapter

ERROR #5002: Cache error: <TRANSLATE>zRead+195^%Net.HttpRequest.1

Any suggestions on this?

Thanks,

Hi,

a Customer of ours comes up with a requirement to improve an existing email business service within one of his ensemble productions. The services fetches emails from a mailserver on a daily basis and extract attached files from this email and send them along with some meta information through the production.

I started with the Atelier Stand Alone.

Now I have moved on to Atelier as a plug-in to Eclipse.

With the Stand Alone I had access to two help topics, the Workbench and the InterSystems Atelier.

Now, as a plug-in I have access to a number of other help topics.

When I do a Help Contents, how do I eliminate those help topics I have no interest in?

Or only do a Help Contents on the topics that apply to me as a Atelier user?

I apologize if you have already covered this, but there is so much to read on Atelier already.

We have 1lakh records in table and while using sql select statement , it is taking more than 9mins to 12 mins to get the records. could you please how to optimize this performance issue if we have more records. how to optimize it.

Hi, Community!

Consider you move data from one server to another or make a deployment with persistent data. What do you do with index globals?

Is it always better to rebuild them or there are some cases when it worth to take them too?

Hi Guys,
Can you please guide me to get rid of this issue. Please find the image files with this post.

Please let me know, before we are developing an API what are all the setup/Configuration(Apache/web server) need to do in my machine.

If any lead would be appreciated.

I don't know, in XMLNamespace parameter which URL need to use.

Hi, folks!

Suppose you have a Caché class with %String property which contains relatively large text (from 10 to 2000 symbols).

The class:

Class Test.Duplicates Extends %Persistent 

{

Property Text As %String (MAXLEN = 2000);

}

And you have thousands of entries.

What are the best options to find entries which are duplicates on this property?

... but let’s first look at error handling.

In short, I wanted to react on CPUusage warnings and alerts with my own actions. It seemed that it was possible in my Caché version (2015.1):
http://docs.intersystems.com/cache201513/csp/docbook/DocBook.UI.Page.cls...

But all my attempts silently failed. Callback code was as simple as possible:

Greetings.

We have one vendor who requires us to send data using TCP

through an SSH port forwarding tunnel that is set up in advance.

UNIX scripts maintain this, and the Ensemble interface uses a TCP Adapter.

I was thinking that Ensemble could maintain the SSH tunnel,

which would improve our detecting of issues.

Has anyone done something like this?

I see that the class %Net.SSH.Session has a method ForwardPort,

but it doesn't stand up the tunnel by itself. Instead, it appears
