Summary

Function: integer llEval( string code );

Returns an integer to see the success of eval´d code.
-1 = Parse error in Eval´d code
0 = Success, but without return in Eval´d code

• string code – a string with different LSL-functions

Examples

<lsl> default { 

   state_entry()
   {
       string code = "llOwnerSay(\"Hello World\");";
       if( llEval(code) != -1 )
       {
           llOwnerSay("...it works !!! Try now more complex :");
           llOwnerSay((string)llEval("llOwnerSay(\" must be 23\"); return 23;"));
       } 
       else
       {
           llOwnerSay("Parse Error in Eval´d code");
       }
   }

   // Output :
   // Hello World
   // ...it works !!! Try now more complex :
   // 23 must be 23

}

</lsl>
