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.
The topic of for/while loop performance in Caché ObjectScript came up in discussion recently, and I'd like to share some thoughts/best practices with the rest of the community. While this is a basic topic in itself, it's easy to overlook the performance implications of otherwise-reasonable approaches.
Hello all; I am using a one-to-many relationship. I have a Claim (one), in a relationship with Lines (many), but the Claim is storing a list of Lines IDs, rather than the Lines storing the Claim Id. This seems upside down, and not what I expected.
A small reflection/question for today... it's true that new IRIS for Health (I4H) releases are more and more powerful each time regarding FHIR capabilities. Nowadays it allows us to consume FHIR resources with extrem easiness, we can connect with end-points in external FHIR servers very easily and make I4H act as passthrough or consume their resources... or, even more, we can define, configure and run a FHIR repository in, literally, less than 5 minutes.
Still a newbie for ensemble, I am trying to convert XML message to HL7 Message. I am using Custom schema for XML structure which includes MSH and PID segments from HL7 Message.
These are the service, process, Operation classes i am using
Business service-EnsLib.EDI.XML.Service.FileService
Business Process-EnsLib.MsgRouter.RoutingEngine
Business operation -EnsLib.HL7.Operation.FileOperation
It's not an easy task to be a master of dates and times, it is always a problem and sometimes confusing in any programming language, we are going to clarify and put a few tips to make this task as simple as possible.

I am trying to grab a specific zip file from a webpage but once I grab the zip file I need to grab a specific file within that zip file and I was hoping someone could explain how to do this or provide an example
With $Property is possible to dynamically get and set values on property of an instanced class and with $ClassMethod is possible to invoke methods from a class.
I would like to know: Is there an elegant way to do Write and Set dynamically on variables without using Xecute?
I'm having trouble parsing XML containing unicode characters which I receive from an external webservice. I believe my file is saved properly with UTF-8 encoding but the SAX Parser still throws me an error.
I have 2 classmethods: 1 general one (get) to make a request to a webservice and return the date, and 1 (getSportsPerDate) to make a specific call and then parse the data.
When using VS Code for Objectscript, is there a way to directly open % classes, like %Library.String, without needing to search for a property of that type and right clicking->"Go to Definition"?
I know it is possible to use "system=1" in the workspace uri definition to see all the % classes, but that tends to clog up the left side viewer with many extra directories. There is also the option in the settings to selectively hide some by defining files.exclude, but it seems fairly complicated to set up a filter for exactly the relevant directories.

We have a bunch of templates on OEX that provide a handy foundation for building a particular application with IRIS. And the basic principle of each and every template is that we take vanilla IRIS images, load code, and files into the image using Dockerfile, and create a new docker image as a solution. And then we develop running this image and rebuilding it when returning to development.
Some developers ask me why we need to build the docker image to work with the code. Indeed, if at the end of the day I need to develop a ZPM package and not a docker image why don't run the vanilla image and load the code and everything in it?
The problem I have with the building image approach is that often I can wait a lot to build an image and it fails on some Objectscript problem in the source that I cannot fix as the image is not building. and

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.
Let's consider these two ways of passing an obj to a function:
//var is a structured obj
(1) do ..methodX(var)
(2) do ..methodX(.var)
In c++ if we pass an obj by reference like in (2) we save a lot in computation because we are not copying the whole object, and when the object is modified within the function it is modified also for everyone.
In this case does (2) achieve any better performance than (1)? Is passing with the "." save any computation? the object is copied anyway?
Is there a simple way of passing obj to a function?
