A way to get around this (for demonstration sake, because
Code:
done < STG_INSTNCE_COMPLTED_01_451_20170112193018.log

is the superior approach to UUOC and there are better ways than using the grep -i inside the loop):
Code:
fnct_dae_V1 ()
{
  var=0
  cat "STG_INSTNCE_COMPLTED_01_451_20170112193018.log" | 
  {
    while read -r line
    do
      if [[ $(echo "$line" | grep -i 'completed') ]]
      then
        ((var++))
        echo "- INSIDE WHILE:var:$var"
      fi
    done
    echo "- OUTSIDE WHILE:var:$var"
  }
}

pid(n)                                                         Tcl Built-In Commands                                                        pid(n)

NAME
pid - Retrieve process identifiers SYNOPSIS
pid ?fileId? _________________________________________________________________ DESCRIPTION
If the fileId argument is given then it should normally refer to a process pipeline created with the open command. In this case the pid command will return a list whose elements are the process identifiers of all the processes in the pipeline, in order. The list will be empty if fileId refers to an open file that is not a process pipeline. If no fileId argument is given then pid returns the process identi- fier of the current process. All process identifiers are returned as decimal strings. EXAMPLE
Print process information about the processes in a pipeline using the SysV ps program before reading the output of that pipeline: set pipeline [open "| zcat somefile.gz | grep foobar | sort -u"] # Print process information exec ps -fp [pid $pipeline] >@stdout # Print a separator and then the output of the pipeline puts [string repeat - 70] puts [read $pipeline] close $pipeline SEE ALSO
exec(n), open(n) KEYWORDS
file, pipeline, process identifier Tcl 7.0 pid(n)
