you are in Caché so this might help:
http://localhost:57772/csp/docbook/DocBook.UI.Page.cls?KEY=GIOD_rmsseqfiles
USE file:position
the equivalent in %Stream,Object is MoveTo 
• method MoveTo(position As %Integer) as %Boolean

Move to this position in the stream. If this suceeds then return true, else return false. Note this implementation is not efficient because it searches from the start of the stream, it can be improved upon in specific subclasses. Note that moving to position 1 will be at the start of the stream, position 2 will be at the second character of the stream, etc.

And then you do your Read or Find..

Hi @Luis Angel Pérez Ramos
I got in fact the same values with my iris community edition.

Test Columnar vs. Row Storage

     1 - Initialize Tables
     2 - Generate Data
     3 - Compare SELECT
     4 - Loop SELECT
     5 - Auto Loop
Select Function or * to exit : 5 Loops to run :25
Set steps by loop

Just in case i misunderstood you.:

  • this is a storage concept for Objects and SQL
  • it is pure Globals and ObjectScript (M) in the core
  • take a look at the Globals used in the example and you see all that you are looking for,
  • and it is just ObjectScript that runs behind the scene

So: what are you looking for ?
And BTW. Its concept ia available for 4+ decades.
It just had no Object, no SQL, no fancy name then,

My Review - before being approved by OEX admins

  • This is a really excellent example on
  • How to publish in OEX
    • a clear to understand description of the target
    • a clean-to-install IPM package
    • a Docker setup easy to follow without any dirty tricks undercover
    • a fast and effective build and install that was tested in practice
    • so you can keep your working environment free of polluting code fragments
    • and a detailed understandable description of how to handle it
  • Big THANKS to @Kurro Lopez

  • Namespace %SYS
  • class SYS.Process is your friend
  • SELECT * FROM SYS.PROCESS
  • in your case :   
    select CurrentDevice from SYS.Process group by CurrentDevice
    CurrentDevice
     
    //./NUL

  • for more details 
    select Pid,CurrentDevice,ClientNodeName,ClientIPAddress  from SYS.Process
