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.
This sample can be used to create Identicons for users of app for example, it can be useful to use in Zen Mojo applications, generating an identifier image based on name of the user by example, but it can be used in others kind of applications too(Zen, CSP etc)
The Caché / Ensemble standard distribution contains in namespace SAMPLES a nice example of a CSP page consuming WebService as a Client. I have modified it not only to display the replies but to feed them back into a Global. I used the classic Hyperevent to achieve this. The replies end up as a log in global^WSREPLY. When there is no input anymore the page closes and goes away.
There are 2 versions with visible and hidden display during operation. dc.WSCSP.reverseVerbose.cls and dc.WSCSP.reverseHidden.cls
How Tax Service, OpenStreetMap, and InterSystems IRIS could help developers get clean addresses

In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.
Recently, I needed to create templates for newsletters. I couldn't find any tools, so I decided to use the CSP (Caché Server Pages) to build the templates.
Let's figure out how to make a newsletter similar to Weekly OEX Digest.
Time travel is like visiting Paris. You can't just read the guide, you have to throw yourself into it. Eat the food, use the wrong verbs, get double the charges, and end up kissing complete strangers.

We are now going to travel through time, that is, we are going to see future and past dates and how to calculate them in different formats. The TARDIS doesn't wait, take the controls and hold on tight.
Hello again and welcome to the next tutorial on this series: Part 4 - Sharing data across router methods. Here we are going to learn how to share a object containing data that is available for read across every router methods.
You're required to complete at least the Part 1 before entering this one. Still, this is supposed to be a really short tutorial, since there isn't much to be said about data sharing.
Methods written in ObjectScript can use pass-by-reference arguments to return information to the caller. Python doesn’t support pass-by-reference arguments, so Embedded Python in IRIS doesn’t support them either. That's it, that's the end of the post, hope you liked it. 😉 But wait, what about the Classic Rock & Roll?
I've been having a blast with the Advent of Code puzzles this year - though I'll be heading into a busy span of time with family soon and will probably drop off toward the end. (At least, that's what always seems to happen - it's a good thing, though!)
Hi - Recently I have been investigating an annoying situation whilst editing ObjectScript classes or routines in VSCode.
What was happening to me was, as I was typing in lines of code into my class (for example, adding a new Method, or changing the Class signature, or a block of code), this would quickly get syntax checked, re-formatted, and compiled - inevitably, (since I would be mid-way through my typing), this would generate compilation errors.
(Originally posted on Intersystems CODE by @Iain Bray) The following code snippet converts all indices in a package to bitmap indices. The subroutine "test" runs the code:
Object Synchronization is a feature that has been around for a while, since Caché days, but I wanted to explore a bit more how it works. I've always thought that database automatic synchronization is complex by nature but, for some particular scenarios shouldn't be so hard. So I considered a very simple use case (OK, perhaps the typical one, I'm not discovering anything... but if it's common and it works, it's good ).
Creating your own commands or shortcut is one of the strongest features of ObjectScript If you create your own Language Extensions to ObjectScript you mostly have to find the proper %ZLANGC00 or %ZLANGV00 or %ZLANGF00 and add the extensions manually.
A few utilities do it already automatically (ZPM, ZME, ..) This utility allows you to add your extensions also programmatically.
Hi Developers, I'm currently doing a demo about building a front end UI doing data analytics and setup a performance test with large data objects, therefore using "Populate Utility" could help me auto generate some sample data that I can play with.
Within this post I would like to share my experience of using Populate Utility, including using POPSPEC Parameter.
The input in today's challenge consists of an encrypted name, a dash, a sectorID, a dash and a checksum between brackets. A name is real if the checksum is equal to the five most common letters in the encypted name.
Now the Classes/Rutines/DeepSee files will be automatically exported to the working directory after saving or compiling and files will be automatically deleted .

Installation
To install isc-dev , you just need to download and import the file isc-dev.xml from last release.
Some ways to import isc-dev .xml file:
Go to Management Portal -> System Explorer -> Classes -> Import and select the XML file.
Do not let the title of this article confuse you; we are not planning to take the InterSystems staff out to a fine Italian restaurant. Instead, this article will cover the principles of working with date and time data types in IRIS. When we use these data types, we should be aware of three different conversion issues:
Converting between internal and ODBC formats.
Converting between local time, UTC, and Posix time.
Converting to and from various date display formats.
This is an attempt to run a vector search demo completely in IRIS There are no external tools and all you need is a Terminal / Console and the management portal. Special thanks to Alvin Ryanputra as his package iris-vector-search that was the base of inspiration and the source for test data.
