When I started in business, quite back in the last century, certifications were not common practice.
Only certificates from European Universities, with just a few from IBM were accepted.
Recruiters were impressed, but managers were more sceptical about.

Having collected a bunch of certificates, this was some disappointment to me.

My later boss explained it to me:

The certificates show that you are strong in learning and delivering tests
Here, we have to provide fast and stable code. This counts.
I had a Dr. Math. from the University that, after 4 weeks of training, was
   not able to write 17 correct running lines of assembly language.
What worth does its certificate have for me ?

This was 53 years ago, and I decided on less noise on paper and more work success

Times are different today

Correct!  |"NS"|  is not allowed as a Class reference.
BUT:   It is a valid syntax for .INT/.MAC  Rooutine   do label^|"NS"|routine
And %objlasterror never shows the class, but the generated .int or .obj you  run.
It's rather a comfort of the COS compiler that your class name matches the .int

I'm fully in Sync with @Dmitry Maslennikov 
Uniqueness is the TOP priority. 
Though you can switch it off for rare cases by the class parameter  MANAGEDEXTENT.

Concerning access speed, naming is not really relevant.
Top level of global storage is a sorted hierarchical directory structure that points to the globals.
So, on average, any global has - with actual storage speed -  the same access time.
And global directory is mostly permanently cached in Global buffers.
BTW: You can list this directory using ^$GLOBAL()

set dir="^$GLOBAL("""")"
for  write dir,! set dir=$QUERY(@dir) quit:dir=""

Strange.
Did you try to load 'upload.csp' directly and just isolated? 
window.close() is the most basic function in JS in any browser.
If that fails, your browser might have a problem.
Do you run some sick PopUp blocker or similar in your browser?

Robert Cemper · Aug 15, 2025 go to post

Well, you have to do it yourself.
Suggestion: Keep a list of the indices processed and skip all followers
For the list you need a small Stored Procedure that you add to
your SQL SELECT in the WHERE clause.

CREATE PROCEDURE SQLUSER.DUPL(value VARCHAR, id INTEGER)
RETURNS INTEGER
LANGUAGE OBJECTSCRIPT
{
 set used=$d(^||dupl(value))
 set ^||dupl(value,id)=$i(^||dupl(value))  
 quit used
}

And in the SELECT

SELECT id, sickindex, . . . . . 
FROM your.data 
WHERE DUPL(sickindex,id) < 1

As a side effect, you create a list of affected indices.
I used a PPG to avoid the need to clear it before use.
If you are interested in the duplicate, you need to change the global name
and add some cleanup before use

Hi Jean,

Taking a look into ##class(%Library.PosixTime)  you see that you shouldn't be concerned on efficiency
It's pretty obvious that the implementation is missing a selectable precision.
so

  • set stripped = $P(str,".",1)

Is similar effective as 

  • set stripped = $E(str,1,19) 

It's not perfect but will be correct and lasting for almost the next 8000 years 😉

Robert Cemper · Aug 14, 2025 go to post

In SMP (System Management Portal), you step to EXLORER and then step into SQL
where you select your TABLE. and can rebuild index


Furthermore, every persistent class  has by default
• classmethod %BuildDeferredIndices
• classmethod %BuildIndices
• classmethod %BuildIndicesAsync
Next variant : use $SYSTEM.OBJ.ValidateIndices()
Details described here  Fix broken index 8 years ago, still valid

Due to limited practice in ZEN I transferred your example to straight CSP and JS

<html>
<head>
<title>Demo for David</title>
<script language="JavaScript" type="text/javascript">
function importExtract()
{
	var url='upload.csp' ;
	var options = 'popup,status=yes,scrollbars=yes,resizable=yes,width=750,height=250' ;
	newwindow=window.open(url,'UPLOAD',options);
    newwindow.focus();
	alert('back');
	}
</script>
</head>
<body>
<h3>Demo for David</h3>
<Input type="button" value="Import Client Consultation Extract"
         onclick="importExtract();"/>
</body>
</html>

in upload.csp I just added this BUTTON to the end ot the main form

	<button onclick="window.close()" style="width: 100px; height: 40px; font-size: 18px;"> Exit </button>
</form>

1.  Use $$DIR^TRACE(dir)  you haven't set a suitable directory
2.  Use $$ON^TRACE(5352)  ; the job you want to trace ==> open file
3:  USE $$OFF ^TRACE(5352) to stop trace ==> close file
4.Now ^TRACE should show the file

I traced my own studio session:

Not sure for Caché 2017 
BUT
Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2018.1.5 (Build 659U) Mon Mar 22 2021 07:12:43 EDT
Has ^TRACE in %SYS
with enough $v(..) and $ZU(..) to look promising 

 W $ZU(5)
%SYS
%SYS>D ^TRACE
 
TRACE utility for Cache. You can signal a process to write a record of all
procedure, function, or subroutine calls to a file. Then use this utility to 
interpret and display the trace. The trace file is named: CacheTrace_'pid'.txt 

Use $$DIR^TRACE(dir) to set the directory where the file(s) should be written
(process must have create/write access to the directory). $$DIR^TRACE() returns
the current directory for trace files. 

Use $$ON^TRACE(pid) to start the trace and $$OFF^TRACE(pid) to end the 
recording. Then just run ^TRACE to see the results. 

Process ID for trace file:
Robert Cemper · Aug 8, 2025 go to post

So  %SYS>d ^TRACE might be a useful start

This utility traces the execution of a process.  Traced processes write events
to a trace file with details about the routine line where the event occurred
and, if applicable, the global reference.  The events available for tracing
correspond to the metrics availabe in performance monitoring tools (PERFMON,
%SYS.MONLBL etc).  Raw data is written to iristrace_<pid>.txt in the
configured directory, and is then parsed and displayed by this utility.
 
 
Trace file directory:   not set
Trace file size limit: unlimited
Trace events selected:  RtnLoad, GloRef, BlockWait, NCacheMiss, DirBlkRd
   UpntBlkRd, BpntBlkRd, DataBlkRd, BdataBlkRd, MapBlkRd, OthBlkRd
 
1) Configure Trace
2) Trace Process (Foreground)
3) Start Background Trace
4) Stop Background Trace
5) Display Trace Files
6) Delete All Trace Files
 
Option?

If I understand it right, you do not just expect a tracking down to some point, 
but also a history of all up and down you did from a certain starting point.
Similar to a TCP traceroute

  • Such a misleading documentation roughly 1.5 years behind reality is not so impressive

quite an interesting hidden feature.

Though testing with _SYSTEM/SYS and %All, this had no visible impact
It is exactly 1 method that breaks in all 4 Nativ packages 
And with %All the rest is available anyhow and working fine.
 

BUT eventually %All is not All enough

Thanks for the input.
A good idea to put the demo in a separate repo
It is just not directly obvious from OEX
works fine, and module.xml looks good. Review placed

>> Naming in ObjectScript has a historic background 
In the beginning, the grand-grandfather of IRIS was a full-stack operating system
And it was running on machines with only 64 KBytes of memory
So saving space in memory was the highest virtue of a developer then.
Consequently, all names were as short as short could be.
Typically using single-character named variables.
And A was different from a to widen the available scope
Over the years, this was kept for backward compatibility and to decrease the fear of upgrades
And I have seen customers running 40+ year old code also in IRIS without any bit changed.

In your screenshot, I see 

$('<div>') simpledialog2(

But W3Schools says:
https://www.w3schools.com/Jquery/jquery_syntax.asp

Basic syntax is: $(selector).action()
  • A $ sign to define/access jQuery
  • A (selector) to "query (or find)" HTML elements
  • A jQuery action() to be performed on the element(s)

I didn't write JavaScript for decades, and I'm not an expert.
BUT: I fail to detect the point after the closing bracket
It was just my Studio that marked it as an error.

I wonder how you expect to know that your input is complete without any terminator.
And according to your example, you also don't have a fixed length:
Withoit an clear signal timeout seems to be the only way to know you are complete.
You may read input character by character without guarantee  
how do decide for 1 or 10 or 100 or 1000  ?
Some ending character (eg. not numeric) or a fixed length is required
