#ObjectScript

I'm sure I've seen this issue reported before, but a search hasn't turned it up.

This appears to happen randomly, but once it starts it doesn't seem to stop ... at least for a while. I attempt to compile a class and compilation fails but produces no error explaining why. Here's an example:

Hey Community,

Our huge thanks to everyone who participated in the Advent of Code 2024! We're pleased to present the participants and distribute all the prizes.

Our congratulations to these developers who have finished all tasks:

🥇 @Abdul Manan (w/ repo)

Here's the final InterSystems leaderboard:

I'm attempting to build a fairly complicated object graph, with nested objects and collections, in order to create a FHIR bundle.

In its most basic form there is a <bundle></bundle> element that represents the root, and there can be a number of nested <entry></entry> child elements.

I'm attempting to represent this as such:

I tried executing the SQL JSON_TABLE query with large JSON string(more than 200000 characters) and I got the below error. I'm curious about this under the hood workflow and how does it reach reaches MAXSTRING.

The Lo-Code Challenge

Imagine the scene. You are working happily at Widgets Direct, the internet's premier retailer of Widgets and Widget Accessories. Your boss has some devastating news, some customers might not be fully happy with their widgets, and we need a helpdesk application to track these complaints. To makes things interesting, he wants this with a very small code footprint and challenges you to deliver an application in less than 150 lines of code using InterSystems IRIS. Is this even possible?

The InterSystems platforms have always offered dynamic documentation of the packages and classes in a namespace, a feature known informally as Documatic. But what if you need to publish this class reference information on a website without requiring the site to be connected to an IRIS server containing the actual classes?

I'm trying to project a series of objects and nested objects to XML, and I'm having difficulties getting the XML representation exactly the way I need it to be. Here's what I'm working with, nothing complicated:

As we keep updating our software, we often realize that we require more and more modern solutions. So far, only one major piece of our software relies on reading barcodes in documents and images. Since Cache did not have a means of reading barcodes in the past, we have always achieved our goals by using a Visual Basic 6 application. However, it is no longer an ideal solution because it is currently complicated to maintain it. IRIS also lacks this capability, but it has recently got an option that makes up for it: embedded Python!

I have a business process that adds data to a global variable on receipt of an HL7 message, and a scheduled task that executes a class method defined within the same business process that removes data from the same global variable. With this in mind it makes sense to consider concurrency and therefore make use of the LOCK command.

My first question is whether this is actually necessary?

As the title suggests, I would like to programmatically export each HL7 schema category as XML, either as a stream object or to a file. How would I go about doing this?

As the title suggests, I would like to programmatically export each individual data lookup table as XML, either as a stream object or to a file. How would I go about doing this?

User-defined aggregate functions have been supported in IRIS since 2021.1.0. I'd wished upon a star for these years ago before finding a secret hacky way to override MAX and MIN in a custom datatype, but didn't get a chance to actually try one out until today.

Many programming languages use the try-and-catch construct to handle runtime errors gracefully. If the code within the try block encounters an error, it will throw an exception to the catch block, where the error handling occurs.
