I am taking over a production system that had some HSLIB and other database routine and class files modified. However, I do not know what was modified .
After many sleepless nights it's a pleasure to announce the newer, better, moderner ObjectScript compiler which implemented pretty much everything you ever wanted to have in modern ObjectScript:
Design objective of this new compiler is to parse reasonable subset of current ObjectScript syntax which will look readable for stranger, and not scare them with 1 letter syntax. The good start for compiler was the old-good COS Guidelines from here https://github.com/intersystems-ru/cos-guidelines
For reasons we mentioned above we do not parse 1 letter syntax. It's declared evil;
We do not handle dotted syntax for the same reason - modern syntax with {} is proper replacement for dotted syntax blocks;
But we not only parse the modern ObjectScript syntax, we have implemented finally the long-standing request which we always dreamed about. Closures!
Class ICT.Experiments.A Extends %Persistent
{
Property Name As %String;
Property Collection As list Of ICT.Experiments.B;
Property Collection2 As array Of ICT.Experiments.C;
}
Class ICT.Experiments.B Extends %Persistent
{
Property Name As %String;
}
Class ICT.Experiments.C Extends %Persistent
{
Property Name As %String;
}
I have the classes above and I can select columns from the array collection by using two joins as follows:
I am trying to experiment the Docker container in our development environment. I have successfully build an image and running the container. When I access the CSP portal home page ( http://<host-ip>:57772/csp/sys/%25CSP.Portal.Home.zen?$NAMESPACE=%25SYS), I am getting the following error:
I have a process that takes data from a CSV file (actually a record mapper object) and creates a nicely formatted JSON string I would love to send this along to a RESTful business operation. However no matter what I try, I continually get <INVALID OREF> errors when trying to populate the object that extends Ens.Request to give it the JSON string.
I can add strings, other objects, you name it - but stuffing a JSON formatted variable/object into another object I want to send someplace is proving to be an impossibility.

when importing one of my classes on the production server into one particular namespace:
I am reviewing some code where the % sign has been used liberally to name arrays that are worked on by different methods within the same class. Apparently it is not good practice to name variables with a "%" sign as the first character because this could overwrite other similarly named variables from other developers, including ISC! Is there another way to make a variable public ?
Need a sample of using %Net.HttpRequest and %NetHttpResponse from Cache to retrieve and then use/reuse a bearer token to send json data to a REST web service.
A good writer is supposed to draw you in with the title and bury the answer somewhere in the article. I suppose this makes me a bad writer – don’t think less of me, my whole feeling of self-worth comes from the opinions of internet strangers!

I am trying to use @() and SYSTEM() from Cache Terminal. I am searching for blinking text . I have found -5 as a Screen Display Option but not aware like how to use on terminal.
Can any one please help ?
I am having a problem with SQL Select, the command in portal is OK, show all items, but when I use a CacheDataAdapter in VB .NET show the message 'Incorrect list format 0>=0'. What could be this message? Because is the same SQL command.
I have a custom process that is parsing HL7 and inserting it into a table. Periodically the inserts fail with # due to error: ERROR #5803: Failed to acquire exclusive lock on instance of....
Traditional databases would wait until the lock is removed then do the insert, but cache fails. I'm sure it's my coding approach.
