your terminal example is just poor , (sorry!)  pauvre
I do it his way, easy to read and easy to follow, (your notation)

this might do it:

Class User.Scott 
{
ClassMethod Clean(infile, outfile) As %Status
{
  set in=##class(%Stream.FileCharacter).%New()
  do in.LinkToFile(infile)
  set out=##class(%Stream.FileCharacter).%New()
  set out.Filename=outfile
  do in.Rewind()
  while 'in.AtEnd {
    set line=in.ReadLine()
    set last=($e(line,*)="|")
    if last set sc=out.WriteLine(line)
    else  set sc=out.Write(line)
  }
  do in.%Close()
  set sc=out.%Save()
  quit sc
}
}

Just to understand your requirements correctly.
- a linebreak  $c(13,10)  would only be acceptable if it follows a segment terminator "|" 
- IF YES Is this just a pipe | or a double pipe || as in your example?
This could be a processing rule to check the last chars of the line
and ignoré the linebreak at a mismatch.   

 

FOUND SOMETHING !

in SMP IRIS you see this header as in Caché / Ensemble

but click to more  has a surprise in IRIS

Select foreground and you get all %session, .... that you look for.

Reverse engineering of the SMP page uncovered this new checkbox to me.
Could be it is documented somewhere

HTH

I could imagine 2 variants:

  • creating a "clone" of the CSP based "synchronous" Queries we know from C/E to have the unique session
  • just using xDBC based tools such as Squirrel, DBeaver, WinSQL, ..... which is probably better since SMP mimics ODBC mode, but doesn't use real xDBC connection
  • external xDBC provides a 1:1 connection as a terminal session would do.     

You are CORRECT
In Caché/Ensemble SMP uses straightforward CSP and you have %session object and %request ...
I verified IRIS 2022.2 and 2022.3:
- SMP runs Queries differently and  neither %session nor %request is visible
by variable »  %inBackground = 1 it indicates working in background
and once completed the Job is gone, but SMP is still around
