Hello,
I am currently maintaining a legacy application that was developed in ObjectScript and accesses data by working directly with globals.
For a new program, however, I plan to access the same global data through SQL-mapped classes.
I have two questions regarding this approach:
..Contains(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"(")&&..Matches(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"^[A-Z][0-9][0-9]$")
I want to do this to match strings such as X98. Community AI tells me this is correct but I get an error in testing. Specifically, this is the part causing the error;
..Matches(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"^[A-Z][0-9][0-9]$")

What do I need to change?
Dear, Community!
I have a concern about using %Stream.TmpCharacter for storage purposes. Reading the class's source code, I can understand a bit about how it works. But I'd like to know from the community how it actually works. Is it necessary to use the .Clear() method to clear this buffer, or is it done automatically upon disposal?
Note: Please forgive my poor English.

In InterSystems IRIS, you can create linked tables using commands, instead of using System Explorer > SQL > Wizard > Linked Tables in the Management Portal:

To create a linked table, use the CreateLinkedTable method of the %SYSTEM.SQL.Schema class. See the class reference for details.
To execute it, follow these steps:
set sc = $SYSTEMSQL.Schema.Hi Everyone, I'm Prakash Hinduja, a financial advisor and consultant. My roots in India now living in Geneva, Switzerland (Swiss). I'm looking for some suggestions on how to get the best performance from Adaptive Analytics 2023.2. I know it uses Adaptive Parallel Execution and automatic aggregates, but I'm curious if you've found any other tips or tricks. For example, are there any specific data modeling choices or system configurations that have worked well for you? I'm trying to make our cubes as responsive as possible. Thanks in advance for any insights!
Hi folks!
Sometimes, when designing a class method and feeding it with more and more useful features, very soon the number of parameters can reach 10 and even more.
It becomes pretty difficult for users of useful methods to remember the position of the important parameter, and it is very easy to misuse the position and transfer the wrong value to the wrong parameter.
Here is an example of such a method (I asked GPT to create a method with 20 params):
ClassMethod GenerateReportWith20Params(
pTitle As %String = "",
pAuthor As %String = "",
pDate As %String = "", // e.g. 2025-09-03
pCompany As %String = "",
pDepartment As %String = "",
pVersion As %String = "1.0",
pFormat As %String = "pdf", // pdf|html|docx
pIncludeCharts As %Boolean = 1,
pIncludeSummary As %Boolean = 1,
pIncludeAppendix As %Boolean = 0,
pConfidentiality As %String = "Public",
pLanguage As %String = "en",
pReviewers As %String = "", // CSV, e.g. "Alice,Bob"
pApprover As %String = "",
pLogoPath As %String = "",
pWatermarkText As %String = "",
pColorScheme As %String = "default",
pPageSize As %String = "A4",
pOrientation As %String = "Portrait",
pOutputPath As %String = "report.pdf"
) As %Status
{
// implementation

New to HealthShare, I wanted to know if there was a way to modify the locations-card within the Provider Directory? I am not seeing a reference to where the Cards are stored within the documentation.
This might be a dumb question but can we have more than one production in a namespace, because we do have running but I thought that I could create a separate one for another project?
Thx
Hi Guys,
I'm a newbie in Python and I've imported this class from another IRIS and for some reason its get an error on %ToJSON()?
I'm also wondering on the need of importing iris at the top given that this code is already running in IRIS!?

Thanks
Hi Guys,
I get the below error when trying to compile an imported class in IRIS, it compiles if I remove

I created a Custom Search Table that extends EnsLib.HL7.Search Table. I saved, compiled, and rebuilt the index however when I go into Message Search to try to use the Search Table, within the conditions the proper fields are not showing up that was defined. It is showing the fields from EnsLib.HL7.SearchTable. I did a build index on both EnsLib.HL7.SearchTable and OSU.HL7.SearchTable.
Class OSU.HL7.SearchTable Extends EnsLib.HL7.SearchTable
{
Parameter DOCCLASS = "EnsLib.HL7.Message";
Parameter EXTENTSIZE = 4000000;

Did you know that 80% of healthcare data is stuck in unstructured formats such as fax? If you take a walk down to Mass General in Boston, you'll literally see a state-of-the-art MRI machine next to a fax machine. Healthcare keeps building incredible new technology but can't let go of legacy technology. We call this the "legacy modernization paradox". This short film follows a care manager at Blue Plan who spends her days doing chart reviews, reading faxes line-by-line, struggling to provide her members the care they need. Everything changes when Blue Plan pilots InterSystems Health Evolve, a solution that transforms her faxes into machine-readable FHIR data ready for AI and analysis. To access our fully working Text-to-FHIR prototype, visit HealthEvolve.de.

Managed Cloud Solutions to Help Streamline Your Health Services.
This demo showcases composing several InterSystems Managed Cloud Services to solve various use-cases.
The video is actually built of 6 short chapters (each ~2.5 minutes long) showing each part of the story, demoing a different service.
You can watch each "chapter" individually if you're interested in a specific service, but there is value in viewing the whole composition and observing the full flow.
[Note the "FHIR IntelliChat" part is not an actual formal InterSystems service, it is just a demonstration of a possibility (based on this solution by @José Pereira) ]

InterSystems IRIS interoperability production development involves using or writing various types of components. They include services (which handle incoming data), processes (which deal with the data flow and logic), and operations (which manage outgoing data or requests). Messages flowing through those components constantly require being adapted to consuming applications. Therefore,Data transformations are by far the most common component in interoperability productions.
In the early stages of data transformation development, the test tool from the Management Portal becomes quite handy.
Customer support questions span structured data (orders, products 🗃️), unstructured knowledge (docs/FAQs 📚), and live systems (shipping updates 🚚). In this post we’ll ship a compact AI agent that handles all three—using:
I have defined a class with a dynamic object property:
My class
Class test.Dyn Extends %Persistent
{
Property json As %DynamicObject;
/// do ##class(test.Dyn).test()
ClassMethod test()
{
do ..%KillExtent()
for len = 100, $$$MaxStringLength - 1, $$$MaxStringLength, $$$MaxStringLength+1, $$$MaxStringLength *2 {
set sc = ..save(len)
write "Len: ",len, " Result: ",$case($$$ISERR(sc), $$$YES: $System.Status.GetErrorText(sc), : "OK"),!
}
}
ClassMethod save(len)
{
set json = {}
set stream = ..getStream(len-8) // -8 because {"a":""}
do json.%Set("a", stream, "stream")
set obj = ..%New()
set obj.json = json
quit obj.%Save()
}
ClassMethod getStream(len)
{
set stream = ##class(%Stream.TmpCharacter).%New()
if len<$$$MaxStringLength {
do stream.Write($tr($j("",len)," ","A"))
} else {
for i=1:$$$MaxStringLength:len {
do stream.Write($tr($j("",$$$MaxStringLength)," ","A"))
}
do stream.Write($tr($j("",len-i)," ","A"))
}
quit stream
}
}The issue I encounter is that if a length of a serialized json property is more than 3641144 symbols, the object fails to save with the following error (either MAXSTRING or STRINGSTACK):
Length: 100 Result: OK
Length: 3641143 Result: OK
Length: 3641144 Result: OK
Length: 3641145 Result: ERROR #5002: ObjectScript error: <MAXSTRING>%GetSerial+1^%Library.DynamicAbstractObject.1
Length: 7282288 Result: ERROR #5002: ObjectScript error: <STRINGSTACK>%GetSerial+1^%Library.DynamicAbstractObject.1Is there a workaround? I need to store moderately large jsons (10-15 Mb) and dynamic object properties allow for a very convenient access.
$ZSTORAGE is set to -1.

Studio's Find In Files finds nothing if CLS routines are included. The error is WIDE CHAR. After using ##class(%Studio.Project).FindInFiles programmatically and then ZW after the same error I strongly suspect that CodeWalkopdatecopyopt in EnsLib.InteropTools.HL7.Cloverleaf.Parser.cls is to blame. I cannot even open this class, unlike other classes from EnsLib.InteropTools.HL7. This error prevents searching even if System Items are excluded and I would peg EnsLib as System. Any remedy besides updating IRIS? Assuming this is fixed in later IRIS versions.
As part of a recent documentation technical project to optimize the search, I needed to use Embedded Python in my ObjectScript code. The main blocker was passing a Python list from a Python class method to a ObjectScript method. Sending the list by reference to the python method, populating it with the Insert() method, and returning the reference to the ObjectScript method resulted in an list with type %SYS.Python, a process that was straightforward but not efficient.
I explored an alternative method: converting a Python list to an ObjectScript list using JSON as the intermediary format.

Our Autonomous Business Intelligent Clerk, or ABiC for short, is a prototype revolutionizing how companies process data and make decisions. Normally, to get insights from data, you’d need IT knowledge or expertise in statistics. But with ABiC, that’s no longer necessary. All you have to do is ask your question in plain language. ABiC understands your interests and intentions, then shows a clear dashboard to guide your decisions. With ABiC, complex data is autonomously analyzed and turned into answers that support users, helping to accelerate business processes. This demo sends the metadata of InterSystems BI cubes to LLM. How does it work? Check out the video for more details!

wget -O qpdf-12.2.0.AppImage https://github.com/qpdf/qpdf/releases/download/v12.2.0/qpdf-12.2.0-x86_64.AppImage
# 2. Make the AppImage executable
chmod +x qpdf-12.2.0.AppImage
# 3. Add executable to system PATH as “qpdf”
sudo mv qpdf-12.2.0.AppImage /usr/local/bin/qpdf
# 4. Verify you’re now running version 12.2.I had a need for a Filter, but did not want to recreate the wheel by creating another Data Lookup Table, so instead I created a Linked Table that points to a MS SQL Table outside of IRIS.
Once I had the Linked Table, I created a Class Method Function that would query the Linked Table and return a 1 if a result came back.
