Hello community;

  • My name is Robert C. Cemper, graduate engineer from Vienna Technical University
  • I'm Austrian, born and still living in Vienna for 77 years. I'm married once and have 3 aged children.
  • Over the years I worked with several big companies in the emerging IT market, like SIEMENS, Olivetti, Digital Equipment, Compaq, ... finally InterSystems. My special story with InterSystems is available in this article 45 Years with Intersystems
  • Actually I'm  "retired but not tired" and follow Developer Community with unbroken interest. Especially because I had a similar proposal 10 years before it finally materialized. My feelings for it are quite similar to a grandfather  
  • My special interests are the core functionalities of the Global Storage, ObjectScript and SQL
  • Working close to the internals is my core competence, but also all network stuff. Actually im focusing on  Docker in the OpenExchange environment. 
  • My top hobby are computers for about 60 years and my whole career was based on it. I started with a console panel with toggle switches for the address and some others for the content. One of my teachers built the first transistor based computer in Europe.  Other hobbies like music, theater, skiing, hiking, biking, travel to other countries changed importance over time. At my retirement I returned to University to catch up with progress in Physics, especially Quantum Physics, Cosmology, Paleology, ... I also added Latin to my set of 4 spoken + 2 written languages.
  • I stopped LinkedIn as I was spammed by unacceptable job offers.
  • Due to health and social limitations I will not attend  READY 2025

#1) in %SYS find the sessions by this Stored Procedure:

#2 Next based on the SessionId I can open the Object
 

%SYS>set sess=##class(%CSP.Session).%OpenId("kTkyVXwgxw")
%SYS>set pid=sess.ProcessId
%SYS>if $l(pid) set tSC=$$DeleteSession^%SYS.cspServer(pid)

The last row was found in  
Class %CSP.UI.Portal.CSPSessions
ClassMethod EndSession

Attention. Not every CSP Session has also a pid !

OK

To Stream needs 1 line 2 statements
 

ClassMethod personsidGET(messageRequest As dc.Sample.v3rest.requests.personsidGET) As %Stream.Object
{
 set stream=##class(%Stream.TmpCharacter).%New(),sc=##class(dc.Sample.Person).%OpenId(messageRequest.pathid).%JSONExportToStream(.stream)
 return stream
 }

To String is shorter (just 1 statement) as you don't need to initialize %String)

ClassMethod personsidGET(messageRequest As dc.Sample.v3rest.requests.personsidGET) As %String
 do ##class(dc.Sample.Person).%OpenId(messageRequest.pathid).%JSONExportToString(.string)
 return string
{

not just Sample.Person but also Sample.Address,
or whatever serial class you refer to require %JSON Adaptor.
then

set person=##class(Sample.Person).%OpenId(3)
>set sc=person.%JSONExportToString(.Jperson)
set zjson={}.%FromJSON(Jperson)
ZWRITE
Jperson="{"LIMIT":103,"Name":"O'Rielly,Xavier E.","SSN":"331-77-5308","DOB":"1957-05-26","Home":{"Street":"8757 Elm Place","City":"Miami","State":"FL","Zip":"92027"},"Office":{"Street":"413 First Drive","City":"Miami","State":"NH","Zip":"83830"},"Age":67,"RowVer":0}"
person=<OBJECT REFERENCE>[2@Sample.Person]
sc=1
zjson=<OBJECT REFERENCE>[13@%Library.DynamicObject]

and there is your dynamic object

do ^ADMIN  indicates that you run a classic straight ObjectScript program.
while WRITE just has 1 direction to act  READ is bi-directional.
READ can send some text as prompt and waits for reply.
The only bi-directinal device I know of are network connections as TCP, UDP, TRM,FTP,..
The common feature is : they communicate out of your IRIS instance.

Inside IRIS  you may do a redirection e.g to some TCP port like |TCP|7000
but then this port is blocked. No other process can touch |TCP|7000.
So you need an external port wrapper to some other port. e.g. |TCP|7100

Then you can handle this bi-directional communication either by sequence
or you have a list of prompts and the expected replies or similar. 

The sequence of operation could then be:

  • have a STARTER that runs in background
    • initiate the external wrapper 
    • run do ^ADMIN
  • start the FOREGROUND 
    • connect to external wrapper
    • send prompts to terminal
    • get replies from external file
    • send it back to port
    • which forwards it to  ^ADMIN hanging in background

 The most tricky point is to handle situations where the communication
if it is not just 1 Prompt :=> 1 Answer  but
multiple Prompts or WRITEs  :=>1 Answer or 1 Prompt :=> multiple Answers.

So I'd suggest instead of an IRIS internal solution rather look for an
external Terminal program to consume and apply your answer script.
