I did a short test fiddling arouned ^Samples.PersonI
an to demonstrate the output.

SAMPLES>Do $SYSTEM.OBJ.ValidateIndices("Sample.Person","",1,2)                   
 
Checking index integrity for class 'Sample.Person'
Begin time:  08/17/2017 21:41:25
 
Verifying data from data map 'IDKEY' is indexed correctly...
Index 'NameIDX', entry ^Sample.PersonI("NameIDX"," CHANG,QUIGLEY H.",39), has differences between master map data and index map data.  Corrected
Index 'NameIDX', entry ^Sample.PersonI("NameIDX"," CHANG,DAN L.",40) missing.  Corrected
Index 'NameIDX', entry ^Sample.PersonI("NameIDX"," CHADWICK,OLGA E.",43) missing.  Corrected

This looks good so far.

to work down a collection of varying number of elements I'd use this kind of loop
in this case it's a double loop

For res=1:1:callresponse.result.Count() {
  Continue:'$IsObject(callresponse.result.GetAt(res)
  For err=1:1:callresponse.result.GetAt(res).Count() {
    Continue:'$IsObject(callresponse.result.GetAt(res).errors.GetAt(err)
    Set context.ErrorMessage= callresponse.result.GetAt(res).errors.GetAt(err).message
    - - - -
    }
 }

This is the paranoic version!
If you trust ENSEMBLE you may skip the check for $IsObject()

Alexey,

with $ZF(-1,command)  you are at OS level.
Nothing  prevents you from extending command to a script that  writes its pid in a file.
using $JOB_".pid" or similar as file name should be enough to  identify it.
So after a moderate HANG your pid should be available.

I prefer this to using pipes or other sophisticated solutions (e.g. listening on a TCP/IP or UDP port, ...)
as you get  an embedded trace for free

online docs don't give a direct hint.

so my shot from the hip: 
selection expression - $select(), $case()  where you get a value based  on a condition
data expression - anything that sets, modifies, composes data.

this is  a quite academic view since  data expressions may contain selection expressions
and selection expressions may contain data expressions.
both variants and any mix of it  are quite common in COS
