In this article, exceptions are covered.

Working with Exceptions

Instead of returning a %Status response, you can raise and throw an Exception. You are then responsible for catching the exception and validating it. IRIS provides five main classes to handle exceptions effectively. Additionally, you can create custom exception class definition based on your needs.

Hello,

I'm trying to add another segment to an HL7 MDM message. More specifically OBXgrp(1).OBX. The addition itself works,. When I look at the message in the trace, the segment with the content can be seen. However, it is not displayed as an OBX segment.

Build Map Status = 'ERROR <EnsEDI>ErrMapRequired: Missing required OBXgrp(1) element at segment 6'
'ERROR <EnsEDI>ErrMapSegUnrecog: Unrecognized Segment 6:'' found after segment 5 (TXA)'

I inherited some legacy MUMPS / ObjectScript code. A code review identified an exclusive NEW and that is not allowed per our coding standards.

The original code contains:

RUN(CALL,DRVNAME)
S $EC=""
S ^TMP($J,"RMPV","DRVNAME")=DRVNAME
N TMPFILE,OLDIO
S OLDIO=$IO
I $G(^TMP("RMPV","SILENT"),1) S IOP="NULL",%ZIS=0 D ^%ZIS I '$G(POP,1) U IO
D INIT^@DRVNAME
D ; scope variables
.N (DUZ,CALL) ; Protect %response
.S IOF="""""",IOM=80,U="^"
.D @CALL
U OLDIO
Q

Hello,

Is there a single ObjectScript operator or method to concatenate two %DynamicArrays?

I'm looking for something that will do the following:

set arr1 = [ 1, 2, 3 ]
set arr2 = [ 4, 5, 6 ]
set arrcombined = arr1.%Concatenate(arr2)

or

set arrcombined arr1_arr2

With end result:

zw arrcombined
arr1=[1,2,3,4,5,6]  ; <DYNAMIC ARRAY>

I can iterate and %Pop over the 2nd array and %Push each popped entry to the 1st array, but I was looking for something more succinct.

Thanks in advance.

As part of a migration project from a bunch of java classes to IRIS, we need to maintain a few jar files due to some external dependencies.

The problem I am seeing is that I cannot pass a byte array ( byte[] ) from ObjectScript to the Java Class. I have tried a number of different ways

I have reproduced in a java class and Objectscript class:
Java Class:

I'm sure I've seen this issue reported before, but a search hasn't turned it up.

This appears to happen randomly, but once it starts it doesn't seem to stop ... at least for a while. I attempt to compile a class and compilation fails but produces no error explaining why. Here's an example:

Hey Community,

Our huge thanks to everyone who participated in the Advent of Code 2024! We're pleased to present the participants and distribute all the prizes.

Our congratulations to these developers who have finished all tasks:

🥇 @Abdul Manan (w/ repo)

Here's the final InterSystems leaderboard:

I tried executing the SQL JSON_TABLE query with large JSON string(more than 200000 characters) and I got the below error. I'm curious about this under the hood workflow and how does it reach reaches MAXSTRING.

You'll find the original text and all my Advent of Code efforts in different programming languages in https://bitbucket.org/janihur/advent-of-code/src/master/

ObjectScript code discussed here is found in https://bitbucket.org/janihur/advent-of-code/src/master/objectscript

The InterSystems platforms have always offered dynamic documentation of the packages and classes in a namespace, a feature known informally as Documatic. But what if you need to publish this class reference information on a website without requiring the site to be connected to an IRIS server containing the actual classes?
