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.
Is there any way that I can check the native type of an object script variable? (similar to the typeof check in javascript)
I see that the DynamicArray class uses the type of the variable for its output, I would like to do something similar when I receive a value as an argument to my method.
How do we trigger a BPL Business Process on a time schedule?
We are building a production that takes a steady stream of (HL7) lab results messages, processes them and stores them in a temporary database table. At scheduled points during the day (eg 0800, 1300, 1600) the database is queried and messages sent on to the downstream system. Aiming that the Processes to be implemented in BPL if possible - but we are having trouble triggering code in a BPL as a scheduled job.
I trying to get the DisplayList data of the ValueLIst from Java using Springboot. when I try to get the DislayList data via java code but I'm getting the VALUELIST data. I don't get any idea to get that DisplayList data. Below is the example
I use Documatic a lot to generate class documentation from comments embedded in the code. Is there a good way to create documentation for SQL views as well? Ideally I want to document each column in the view with HTML markup similar to how I document each method of a class with Documatic.
I've been trying to figure out how to use an ObjectScript class to search other classes for specific strings. To be very specific, I want to be able to search business rules to see if a particular DTL is in the rule. We have some orphaned DTL's in our Ensemble productions and I want to make sure that they're not being used.
I am still a beginner with COS and am struggling with these concepts. While digging through the official documentation will eventually tell you everything you need to know, getting started is nevertheless not an easy feat...
Is it possible to create a "lists/array/multidimensional 101" page for beginners? And, for instance, its interaction with $data, what it means to use "as list of something" or "as array of something", how to walk lists, how to add/remove elements, how to extract sublists etc?
– I want to “copy” a file to another, appending if the file already exists. The below code works, except it overwrites the new file, rather than append. The documentation says CopyFile will append

The Season's holidays are fast approaching, and it's time to get ready for them! Join the Advent of Code 2024 with InterSystems and engage in our ObjectScript challenge!
Our development server is set up to automatically keep the .INT code of compiled classes and routines, but the live servers are set to not keep the .INT code.
I know how to set the system to keep this code ($SYSTEM.OBJ.SetQualifiers() ?) but what are the ramifications of keeping this code on the live servers? Is it just a space issue? I always thought it was to keep the code more private.
I have a case where I am creating a PDF file from an Encoded String, and I need to transfer this file over to another server. I was wondering since this is PDF file if I could just invoke the FTP.OutboundAdapter within my Object script that is creating the PDF from the encoded string. Is this possible? Does anyone have an examples of using EnsLib.FTP.OutboundAdpater within their Object Script?
Is using ASP.Net Core 2.0 with Cache Object Script possible? I have it successfully working with .Net 4.5 using the supplied .Net 4.5 Dll file by Intersystems. Is there an updated Dll file for .Net Core 2.0?
I'm receiving in one of our interface a XML file as a %Stream.GlobalBinary, and in the source Application that produces this XML file, the user sometimes add a special character that force the XML file to have the header encoding to UTF-8, instead of ISO-8859-1 :
Since cache is an OOP language, how can I create 2 methods with the same name but different parameters? Right now when I try that I get a compile time error!
Element name conflict [80670005] : Method mymethod

In this short article I would like to present an example of use that surely many of you who work with IRIS as the backend for your web applications have faced on more than one occasion and it is how to send a file to your server from the frontend.
when I using ObjectScript Trigger Code , I want to get whether the fields has changed by using "{fieldName*C}" , actually, fieldName in "{fieldName*C}" is a real field name ,but in my code, fieldName is a variable as follows:
I'm running into an issue performing UPDATES that I'm not getting on INSERTS. It's probably obvious, but I'm just not seeing it and could use a little help.
I'm going over an HL7 message and depending upon varying criteria, the relevent variables will get items added to them like the following:
Set patientId = pRequest.GetValueAt("PID:3")
Set sqlColumns = sqlColumns_",patient_id"
Set sqlValues = sqlValues_",?"
Set par($i(p)) = patientId
After compiling the variables, I check to see if accession number is found in the table.
One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.
Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.
The trick is how you transfer an array to work with into a function.
One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator.
Below you can find a very simple example which illustrates the thing.
