But be aware that variables you pass to your method are either explicit as in your example

or are variables in global scope.   eg. %par1, %par2, ...

a solution with NO $TRANSLATE

 set str="aN d.ef123$eR=xx?,yWz"
 for i=1:1:$l(str) s:$e(str,i)'?1(1AN,1".",1" ",1",") $e(str,i)=" " 

 aN d.ef123 eR xx ,yWz

From docs.

see: Host Variables

You are using instead object property references.==>    objSearch.StartIndex,  .....
Load your properties into local variables and it should work

The TERMINAL is only available in the Windows installation. From the Cube menue.
 

On other platforms you require csession command from your OS shell.

Alexey,

you are perfectly correct. My intention was to demonstrate that the ancient approach of 
OPEN and USE command parameters dating from the previous millennium is still valid.

$LB() is definitely the more general and flexible solution. 

a very wise step !!

I think you have it in COS since Strings became almost endless.
Par #2) of my answer showed it:

and the method end:

ClassMethod method(parameter as %String(MAXLEN="") {
   for par="SERVER","PORT","NAMESPACE" 
   set @par=$P($P(parameter,par_"=",2),":") 
   zw @par 
   #; now do something ...   
}
SERVER="127.0.0.1" 
PORT=1972 
NAMESPACE="SAMPLES"

Log In over Terminal as Privileged User and move to Namespace %SYS   and fix your Security 

USER>ZN "%SYS"
%SYS>DO ^SECURITY
