InterSystems ObjectScript is a scripting language to operate with data using any data model of InterSystems Data Platform (Objects, Relational, Key-Value, Document, Globals) and to develop business logic for serverside applications on InterSystems Data Platform.
I am currently looking for a Cache ObjectScript Developer. Please see job description below. If you are interested please send an email to paul.lilienfeld@libertyits.com
Our company is in the process of converting our software for use in Intersystems IRIS and one of the major sections of the software makes use of a custom statically-linked C library using the $ZF("function-name") functionality. During this, I found out that the process for setting up the C library to be used within the database platform has changed significantly between Cache and IRIS.

This article is intended to be a simple tutorial on how to create ODBC connections and working with them, since I found starting with them a little bit confused, but I had amazing people to take my hand and walk me through it, and I think everyone deserves that kind of help too. I'm going to divide each little part in sections, so feel free to jump to the one you feel the need to, although I recommend reading everything.
t's also an example for a customized command extension (ZZJSN) in Caché & IRIS
This is the Caché version for fast JSON formatting but it also works in IRIS. Requires package ZPretty To allow parallel existence in IRIS this is named ZZJSN
In this article, I'll show you how to run code at compile time with ObjectScript macros.
Here's a use case that recently led me to use this feature:
As part of a medical application developed for more than 20 years, we have a large number of parameters. Although we have procedures for documenting these settings, it can be helpful to have a quick view of which settings are actually used by the application code.
We have a use case whereby very large HL7 MDM messages, which contain many OBX segments, need to be processed by a custom business process. Part of the process is to iterate over each OBX segment and set a value in the same field for each segment.
I purchased an HP LaserJet M101-M106 printer, and I'm trying to print via the Windows cache device, but I can't get it to work. I can send it, but it doesn't print. Physical device name: |PRN|HP LaserJet M101-M106 Type: Other Subtype: P-DEC Open Parameters: “W”
Could someone help me with what might be happening?
Instead of returning a %Status response, you can raise and throw an Exception. You are then responsible for catching the exception and validating it. IRIS provides five main classes to handle exceptions effectively. Additionally, you can create custom exception class definition based on your needs.
N.P.M. is a Project & Task Management app that uses InterSystems IRIS and Bootstrap 4.
No Project Mess is created to help developers and small business companies to reduce complexity in their daily problems, with a simple and intuitive projects and tasks management software.
It offers different views for your tasks, from a spreadsheet, kanban, calendar, or even Gantt!
You may think it isn’t too difficult to get from label+offset^routine to the actual source line responsible for the error. For an expert it isn't that hard... most of the time. But there are enough oddities and special rules that even an expert can get it wrong, whilst spending a lot of time trying to get there.
gj :: locate is the latest tool from George James Software – it debugs any error, class or routine by converting the location of an error in compiled .int code to the corresponding location in your source, and then taking you right there.

First, let me wish the developer community a Happy New Year! We hope to bring you many good things this year, and today I'd like to introduce the latest version of the Intersystems Language Server extension to VS Code. Most Language Server improvements are experienced via the ObjectScript extension UI, so you many not be aware of the many improvements in areas like Intellisense and hover overs that were released throughout 2024.

Looking for a fast, efficient IDE for developing ObjectScript code?
Check out ObjectScript with Visual Studio Code, a new video from Online Learning, which shows how to export ObjectScript packages from the InterSystems IRIS server and write ObjectScript classes and methods with Visual Studio Code.
This is a sample to use %JSON.Adaptor class available in IRIS to produce a snapshot of your object.
The sample consists of 2 classes that are variations of what was known in Caché/SAMPLES as Sample.Person. Be aware that the possibilities are limited by %JSON.Adapter and how you make use of it.
Once in place, you create some test data by Populate(). You select an object and take a snapshot. You apply changes to your object and take another snapshot. And see the difference.
The InterSystems ObjectScript language does not allow you to define methods of the same name with different arguments. It is generally classified as a programming language called a dynamic language.
In ObjectScript, you can freely control which arguments are used when executing a method, so unlike languages such as Java, which are not dynamic programming languages, there is no need to strictly distinguish methods by the number of arguments at the compilation stage.
