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.
My query that I am running on my Custom SQL Inbound Service has columns that are larger than the typical string length. How do I enlarge the SQL Snapshot Column limitations
Class osuwmc.Epic.Clarity.I want to append items to the list inside a for loop
Example:
set mylist = $ListBuild()
for i = 1:1:5 {
set item = "item"_i
set mylist = $ListBuild(mylist,item)
}
zw mylist
The output should be:
mylist = $lb("item1", "item2", "item3", "itme4", "item5")The code snippet written above is not working, looking for correct way to do it.
In the process of trying to get more familiar with Objectscript I decided to try to build a general priority queue since I wasn't able to find an implementation anywhere. My though process for implementing this followed this general path.
My first though to try to make this work quickly was to implement a binary heap and my first attempt at this used a multidimensional to build it. This version was relatively efficient, worked for strings/numbers natively, and worked for objects be letting the user override the comparitor.
Class pqueue.Hello, dear colleagues.
I need to connect to a remote JavaGateway from an Ensemble service.
I am trying to use the EnsLib.JavaGateway.Service with a remote host where the JVM is running.
I can successfully ping the remote Java Gateway from EnsLib.JavaGateway.Service, and Ensemble reports that the service status is OK.
There are no network issues, and all necessary ports are accessible.
My requests work without any problems when I specify localhost in EnsLib.JavaGateway.Service.
Hi colleagues!
Yet another time I figured that there is no super-simple way to display error from %Status variable, but I need it relatively often in a terminal.
Yes, I know about $$$ Macro, but they are not superhelpful in a terminal.
My usual behavior is to try to remember by heart or copy from somewhere the formula:
USER>w $System.Status.DisplayError(st)
I have created a class file that I want to execute daily to gather Metrics (Message Header, Space Available, etc..) and write the data into a Cache table. Now that I have written the class I want to add it to the Task Scheduler within Ensemble to run every morning. How do I go about getting the class file created as a Task within the Task Scheduler? The Documentation isn't as clear cut for creating custom tasks as one would expect.
I already mentioned in a Previous post I am trying to build a list from a repeatable field within a HL7 message. I figured out how to build the list by using a context list string variable within the Business Process (BPL) and doing a
do context.<variable>.Insert = <value>when I am looping through the field. I want to do it one step farther though... I want to search the list to see if the value exists before I do the insert. I only want to insert if the value is different than what is in the list already.
IF $LF(context.Facilities,##class(Ens.Rule.FunctionSet).I have a repeatable field within HL7 that I want to create a List from. Do I have to initialize the List by using $LB, or can I just use $LI to keep adding on to the end of the list as it is looping through the field?
I was thinking about how to create a new parameter in a method, similar to Output or ByRef...
What documentation can I read to learn more about this?
I want to create a parameter customized.
I have been trying to get to grips with the new dot Net Gateway used in IRIS as the import of the DLL to construct proxy classes is no longer supported in IRIS I have a third party DLL that when I try to instantiate throws an error complaining about the class not instantiated as it does not support parameterless constructor .I am using this new

do gateway.addToPath(myPath_"\DotNetGatewaySamples.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.

The question is straight forward. Is there a way to do that? I've searched docs but no result
Hello, I try to develop a REST interface where I need to interact with legacy MUMPS routines. How can I pass in input to a Read without modifying the legacy code?
I think in linux I can execute command < inputfile to read from file, but how does it work in ObjectScript?
Anyone know how to subtract three hours from
If $ZDATETIME($HOROLOG,3) returns 2025-01-30 10:17:04, I would like $ZDATETIME($HOROLOG,3) - 3 hours to return 2025-01-30 07:17:04
We have some ObjectScript code in a custom business process:.png)
When Log Trace Events is ticked on the business process in the Production view in the management portal, the argument is obviously computed.
Our question is whether the argument is computed when Log Trace Events is not ticked? Don't want to accidentally include something in a $$$TRACE() statement that takes enough computation to make a performance difference when released to production, even though the final output is not written to the event log.
The documentation at https://docs.intersystems.com/irisforhealthlatest/csp/docbook/DocBook.U…
Case-sensitive: variable names (other than the system variables) are case-sensitive. Names of classes and their members, names of routines and their entry points, names of include files and macros are all case sensitive.
Consider "fully qualified" class name: Package.subpackage.ClassName
What is the class name mentioned in the documentation? Package.subpackage.ClassName or ClassName ?
Hi Community,
Watch this short exercise in writing basic code snippets in InterSystems ObjectScript using Copilot in VSCode and the GPT-4.0 engine. This screencast covers "Hello, World," global manipulation, class creation, and building a simple REST API application.

Hi Everyone!
The Certification Team of InterSystems Learning Services is currently developing an InterSystems ObjectScript Specialist certification exam. Earlier this month we reached out to our community for feedback that will help us evaluate and establish the contents of this exam. We are still currently accepting responses and would love to hear your feedback!
Please note that this is one of two exams being developed to replace our InterSystems IRIS Core Solutions Developer exam. You can find more details about the other exam, InterSystems IRIS Developer Professional exam, here.
Hi Dev Community
I thought i would share a little method I knocked together to traverse and compare 2 JSON objects for basic equivilance. I'm currently working on some data migration, and wanted a basic sanity check to validate that the JSON output is basically equivliant between the old and new, excluding a few things like timestamps.
It's a basic little recurvsive method, that will bubble up any differences over a nested structure. It's very low tech, as that's all I need it to do, but I thought it might be useful for others?
Hi folks!
I'm building a very simple REST API.
But before testing it via a Web Server what I want to make sure that REST API methods work in principle.
Is it an easy way to "fake" the web-server request and get a result e.g. of the method with signature like that?
ClassMethod GetAllRecords(pRequest As %CSP.Request, pResponse As %CSP.Response) As %Status
e.g. calling it in Terminal?
Hello!
This article is a small overview of a tool that helps to understand classes and their structure inside the InterSystems products: from IRIS to Caché, Ensemble, HealthShare.
In short, it visualizes a class or an entire package, shows the relations between classes and provides all the possible information to developers and team leads without making them go to Studio and examine the code there.
If you are learning InterSystems products, reviewing projects a lot or just interested in something new in InterSystems Technology solutions — you are more than welcome to read the overview of ObjectScript Class Explorer!
Hi all!
In this article I would like to review those VS Code extensions which I use myself to work with InterSystems and which make my work much more convenient. I am sure this article will be useful for those who are just starting their journey to learn InterSystems technologies. However, I also hope that this article could be useful for experienced developers with many years of experience and open up new possibilities for them when using VS Code for development.
| “At the request of the survivors, the names have been changed. Out of respect for the dead, the REST has been told exactly as it occurred.” |
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. Please take a quick read over the Language Server's CHANGELOG and find out what you missed. Most recently, version 2.7.
In this article, exceptions are covered.
Working with Exceptions
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.
These exceptions are different from %Status, so you can't directly/efficiently use the exception object with $SYSTEM.OBJ.DisplayError() or $SYSTEM.Status.DisplayError().
Hi,
I found an issue while fetching records from FHIR DB, I am getting below error thou FHIR repository have the records with the corresponding id

Hello All,
I need help Integrating the vendor-provided code into the current code to check if the data is an array and if it is, iterate through each item using a for each loop. Also, I need to hit every error handler code mentioned at the bottom along with the transform in both instances.
My Current Code:
/// Given a patient number in a JSON string format, this includes required transformations and makes use of
/// the MPI Query Handler to pull basic demographics from Epic.
Class CUH.Proc.DCIQGetPatient Extends Ens.
Hello,
I'm trying to add another segment to an HL7 MDM message. More specifically OBXgrp(1).OBX. The addition itself works,. When I look at the message in the trace, the segment with the content can be seen. However, it is not displayed as an OBX segment.
Build Map Status = 'ERROR <EnsEDI>ErrMapRequired: Missing required OBXgrp(1) element at segment 6'
'ERROR <EnsEDI>ErrMapSegUnrecog: Unrecognized Segment 6:'' found after segment 5 (TXA)'
.png)
// HL7-Nachricht klonen
Set response = msg.%ConstructClone()
// OBX-Segment erstellen
Set tSegmentOBX = ##class(EnsLib.HL7.Segment).We have a vendor that can only send us a uu-encoded PDF. Is there a way to decrypt it in Ensemble?
Thanks
