Thanks, I got the solution based on your answer.  I also created 
different slicing functions.  They work just fine without the 
need for conversion:

```d
     T solKes(string str, size_t a, size_t l)
     {
       import std.conv;
       const b = a + l;
       return str[a + 1..b].to!T;
     }

     T kalKes(string str, size_t a, size_t l)
     {
       import std.conv;
       const b = a + l;
       return str[b - 1..b].to!T;
     }

     T sagKes(string str, size_t a, size_t l)
     {
       import std.conv;
       const b = a + l;
       return str[a..b - 1].to!T;
     }

     T tekKes(string str, size_t a, size_t l)
     {
       import std.conv;
       return str[a..a + l].to!T;
     }
```
Thanks again...
