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 am still learning the platform for a student project and have to do some streaming and data analysis next. Since for my case I have no "live api" I wanted to just stream json files and output the data as it comes in from the files. (basically to emulate a incoming data scenario)
So thanks to the documentation and community posts I have figured how to create a stream and read data from a JSON but since I'm also new to JSON I have some parsing problems. I don't know how to access subarrays/sub-objects via objectscript.
Typically, I have time to review the documentation, which I'm sure is here. However, I have a workaround (TEST1) but I was wondering if anyone could assist me in advising how I would need to adapt the curly brace snippet (TEST2) to provide the same result.
From within the context of an instance of EmbedObj, how can I navigate to the containing instance of "ContainterObj" and find that value of its Foobar property?
I was wondering if there is any way to count elements from an array. I guess not as an array could be multi-dimensional and that would be a problem to return the number of elements inside the array.
I'm trying to send emails to a distribution list but it doesnt work. However, When I send emails to individual emails it works fine. Is there a configuration that I need to be checking or enable?
Sometimes, we need to copy part of the properties of an object into a different one. The simplest thing would be to do the following:
Set obj1.FirstName = obj2.FirstName
Set obj1.SecondName = obj2.SecondName
What happens if the object contains a large number of properties? or we just want to extract an important group of data, and complement the information in another object?
A function iterates global ^data(a,b,c) with $order using 3 nested for-loops. At certain point, for example with a=10, b=20, c=30, the function exits and later has to resume the iteration from the same point. What could be easiest way for it? My solution looks too ugly.

I've collated a list of public Caché Projects that I've been able to find through GitHub topics and various other searches, let me know if I have missed any and I will add them to the list.
I need to perform some processing-heavy operations on a set of input objects and I would like to utilize more than a single processor core to do the heavy lifting.
Is there any way to call methods in parallel and wait for the results in a blocking way?
Basically, I am looking for an equivalent of the pythonese
with Pool(n) as p: results = p.map(function, data)
Set httprequest=##class(%Net.HttpRequest).%New()

I want to disable / turn off the visible cursor and then re-enable from with a Cache MUMPS (COS) routine. Can anyone advise please ? I am using the free Intersystems Cache installation (CachePCkit V2017.1) on Windows 10 for my own use & personal development.
The base class Bmap.Person defines persons within an organization distributed by various countries. All records are indexed by (Country, PersonalId). this structure doesn't allow use of bitmaps.
So a wrapper class Bmap.PersonQ around the data eliminates the top level of the index (Country) and isolates the PersonalId (%Integer, MINVAL=1). We are ready to use a Bitmap index.
A few performance figures on 300010 generated records. You see that Relative Cost are sometimes quite misleading.
I'm trying to learn how To use SQL in CACHE, so I hope I don't bore you with "Dumb" questions....
I'm getting "ERROR #6022: Gateway failed" message following this line of code.

This line of code comes from an example I found in the documentation. pQuery is the "Select" statement setting up the variables and tables I'm trying to pull information from.
