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.

I've found a couple of methods that will tell me whether a package is mapped from another database, but not which database. Is there such a method/routine?
Forgive me if this is a rather low-level question - I am a physician informaticist who is learning cache/mumps for the first time. I am sure this probably relates to some setting but I can't find a similar issue anywhere.
When I create a list, and then try and return that list - I get a bunch of symbols back along with my results, or sometimes I just get symbols.
I pasted a screenshot below. Thank is advance for the help!

I have been creating a class to handle file encryption by using GPG keys. I pushed my code out today and my encrypt and decrypt methods weren't working. About a half an hour later in troubleshooting I found out that it needed to be a syntax change. My method has three parameters to it. Examples below:
This is how I was calling it in the test system with no issues:
do gpg.Encrypt()
This is how I was having to call it in my production system to work with no issues:
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?

Say you have a DICOM document with an input information sequence with many sequence items. You could access every item one by one by looping and querying the path by passing it to the GetValueAt method as demonsrated below.
This works but there are some performance issues on my system if the document has to be read for each query (as far as I know, that is the case on my system). Is there a way of querying a path, which would return the sequence items as an array? I think I am missing something. With 900 items the process takes around 20 seconds currently.

I want to call the REST endpoint and return the list of objects. I`ve created the method but it displays an error: <METHOD DOES NOT EXIST>GetAllPersons+10^Lab3.RestClient.1 *Count,%ZEN.proxyObject
In this article, I'll show you how to run code at compile time with ObjectScript macros.
Here's a use case that recently led me to use this feature:
As part of a medical application developed for more than 20 years, we have a large number of parameters. Although we have procedures for documenting these settings, it can be helpful to have a quick view of which settings are actually used by the application code.
When for any particular reason I need to update a record and don't want to pull the triggers, the keyword %NOTRIGGER can be used. But I've been trying to do the same when I change the row using the object approach, but I can't find it. Anyone knows if it's possible to avoid pulling triggers when working with objects?
Sadly, the utility "DISABLE^%NOTRIGGER" doesn't seem to exist ;-)
Following Issue: When I update a SQL table like (update OnlineV3Admin.ParameterApp set popuptext = '' where ID = '1') and then read it for my Json WebService there is a /"x00" in my Json.
What is the best option to disable that? I need here a empty String and not /x00.
While creating my latest examples for the JavaContest I faced the need to communicate with my code from a program in IRIS to my Java code.
Communication with |CPIPE| worked as READ or WRITE but not both? In the Documentation Named PIPEs are explained rather shortly. "Once open, a pipe acts like an ordinary device." Not so precise. I failed to achieve my expected READ/WRITE as TCP would offer.
Excuse if this is obvious to Python programmers but for those crossing over from ObjectScript this may be a useful tip.
The scenario is developing some Embedded python commands.
Testing out functionality is being confirmed via the shell:
$SYSTEM.Python.Shell()
Python 3.9.5 (default, Mar 14 2023, 06:58:44) [MSC v.1927 64 bit (AMD64)] on win32
Type quit() or Ctrl-D to exit this shell.
>>>
When Python evaluates an expression in the shell, it prints the result of the expression to the terminal.
We would like to store a list into a global. The need is to get the full Web Service's Response Message, because of currently, our Operation sends the message to the Process, whith an empty list:
We have created a copyList which is a clone of the list which is being returned from the web service client:
Announcing gj :: locate. A simple extension for VS Code that will help you get to the source of your errors.
In VS Code, using either the Serenji extension or the basic InterSystems objectscript extension, this small add-on will open the appropriate class or routine and position you at the exact line where an error occurred.
No more tedious counting of lines to find <UNDEFINED>zCredit+206^Ledger.Invoice.1. Instead, with gj :: locate you can get there with just a couple of clicks.
I'm new to the Intersystems development world and I've been trying to figure out how to make a REST API using ObjectScript. I found a tutorial that I've been following that has been great and I'm trying to translate what I've learned to live data.
