In you have tried to run the code sample I posted in this thread, I  
just discovered that either my email app, or the HTML coding on this  
page apparently recognizes  a "backslash r" (I can't use the actual  
"\" character with the "r" in this sentence for that very reason) as  
a carriage return. Hence, in this loop you will need to substitute  
the actual backslash r characters inside double quotes to get it work  
as designed.

for (i=0; i<3; i++)
    {
       for (j=0; j<3; j++)
     {  // printf(" %d", testArr[i][j]);
       CFStringAppendFormat( mutStr, NULL, CFSTR( " %d" ), testArr[i] 
[j] );
     }
     CFStringAppendFormat( mutStr, NULL, CFSTR(  -- put  double-quote  
backslash r double-quote here -- ) );
    }
   return( mutStr );
}

Apologies for the inconvenience.
