The correct way is:

ClassMethod ind() [ PublicList = (active,reactive) ]
{
  new active,reactive

  kill info
 // the above command (kill info) is a kind of NOP (no-operation)
 // at the time of entry into a methode there are no variables,
 // except those in the public list (if defined)

  set active = 1
  set reactive = 2

  for i="active","reactive" {
    set info(i)= @i
  }

  zw info

  break
}

If you want to use name-indirection in a procedure block, then

- variables, used by indirection, must be made public (via PublicList)
- and, depending on the situation, should be saved with the NEW command

Maybe you want something like this:

set data1 = "%sqlcq.something.value.foo"
set data2 = "sqlcq.something.value.bar"

for x=data1, data2 { if x ? .1"%"1"sqlcq".e { write "OK" } else { write "NOT" } w ! }

Your output should be:
OK
OK

"like a centipede with a wooden leg: 99 times tic and 1 toc
the stream is then truncated and still requires extra coding"

That's the whole point!
If we turncate the stream to $$$MaxStringLength, no matter where (in a calculated property or in a GETter method), just to present this (string)value to a variable, a function or whatever, then we can instantly stick to a string.

By the way, it's possible to store $$$MaxStringLength bytes in a local or global variable.
Properties of classes are stored in globals as $listelements, so the maxlength for a single string property depends on things like count and types of other properties in the class and not least, does this class extends %Persistent or extends another class(es) which extends %Persistent - in this case we need some extra bytes for those (extended) class names too.

HANG command exists.

You can put between each command (if you have enought time ;-)) ) an hang command:

while response.StringValue="Processing" {
hang 5 // pause for 5 seconds
// get new response
}

Hello Kevin,

if I anderstand you correctly, several your Cache systems (development, life, ...) will store their files on a third server (possibly on a file server) and you want to put the files from each (source) Cache (instance) into a different (target) folder, where the folder name being the "name" of the source Cache system - am I correct?

If yes, I think, your best choice ist:

...\hostNameOfCache\instanceNameofCache...

or, as John Murray suggested

...\GUIDofCacheInstance...

or just a fixed string like

...\kevinNotebook(development)...

You can put (John's) GUID or my "fixed string"
in a (possibly system) Global like ^%Zconfig("path")=...

Why?
Things like MAC- or IP-Addresses can change more often then you think. Especially IP-Addresses will change, hence are there DNS servers.

On the other hand, it's uncommon to change host- or instance names (of Cache or of whatever installation).

Your IP-Address preference has an other downside too. Many servers have more then one IP-Address (and if they do not have one today, maybe tomorrow!).

If you persist to take the systems IP-Address, here is, what you wanted:

set iplist = $system.INetInfo.GetListOfConfiguredInterfaces(0)
for i = 1:1:$listlength(iplist) zw $list(iplist,i)

You can do it either this way:

set OrgTypeId = $piece(line, ",", 2) // assuming, item 2 is an OID of ZenCrm.OrgType
if ##class(ZenCrm.OrgType).ExistsId(OrgTypeId) { set rec.OrgType = ##class(ZenCrm.OrgType).%OpenId(OrgTypeId,0) }

or this way:
do rec.OrgTypeSetObjectId($piece(line, ",", 2))

You are comparing apples wih oranges!

The line  (your case 1):

set dat=$lg(^TestD(id))    //dat=$lb("a","b","c","d","e")

sets dat to the FIRST list item (if present, or to "", if the list item is NOT present) of ^TestD(id)  but ONLY if ^TestD(id) is defined AND it is a Cache list.

In elsecase, you will get an <UNDEF> if ^TestD(id) does not exists or an <LIST> error, if ^TestD(id) exists but the content is not a list!

The line (your case 2):

 set dat=$g(^TEST2(id))   //dat = "a#b#c#d#e"

sets dat to the content of ^TEST2(id) , if  it exists or to "", if there is no ^TEST2(id)

On-the-fly and untested:

set del=<your_csv_delimiter> // <;>, <tab>, <whatever...>

 while'stream.AtEnd {
        set line=stream.ReadLine()
        write line,! // this is csv

       set json=[]

     for i=1:1:$l(line,del) do json.%Push($p(line,del,i))

    write json.%ToJSON(),!  // or whatever other action you need...
}

The  short answer ist:

a) look for Mnemonics 

b) write /cup(line, column)

c) use ?tab

For example:

 write #, "Hello", !, /cup(3,25),"Let's go....", !, "And now", ?20, "we are in column 20", !

I think, your best bet is:

write $zstrip($zstrip(text,"*c"),"<=>w")

because you want to remoe ALL (i.e.: *) control chars but only SOME (i.e.: <=>) whitespaces.

You could try something like:

set chars=$c(0,1,2,3,....31, 32 /* blank */, ...<maybe other control chars, above 128>)

write $tr(text,chars)

Class your.class
{
Property Colors As list Of %String;


ClassMethod toJson(list) As %String [ SqlProc ]
{
    s json=""
    f i=1:1:$ll(list) {
        s:i>1 json=json_"," s item=$lg(list,i)
        if '$ld(list,i) { s json=json_"null" }
        elseif item="" { s json=json_"""""" }
        elseif $lv(item) { s json=json_..toJson(item) }
        elseif $num(item,".")=item { s json=json_$fn(item,"N") }
        else {
            f c="\","/","""",$c(8),$c(9),$c(10),$c(12),$c(13) s item=$replace(item,c,"\"_$tr(c,$c(8,9,10,12,13),"btnfr"))
            f  q:'$locate(item,"[:cntrl:]",0,j,v)  s $e(item,j-1)="\u"_$e($zh($a(v)+65536),2,5)
            s json=json_""""_item_""""
        }
    }
    
    q "["_json_"]"
}
}

select your.class_toJson(Colors) from your.class

gives you the expected result . If you prefer  a direct  use of globals, then use

write ##class(your.class).toJson($lg(^your.global(theOID),theSlotNumber))

Cache dies not like an object property as a left side argument,

but you can solve the problem much simpler:

set context.NewID=$tr($j(context.PatientID,10)," ",0)

By the way, if your solution would work, the result would be longer then 10 chars

for example, if context.PatientID=123 then you

would get: "000000123000"

instead of: "0000000123"

my quick test says there are two chars, CR and LF, on an AIX and on Ubuntu

Maybe, your problem has nothing to do with Cache?
