People make mistakes all the time with dynamic data structures, forgetting that they are implicit pointers (or getting run time errors when they change the type of a variable from a static into a dynamic one). Passing the address of the first element is however always correct. The only downside is that the index of the first element may change, although for strings it won't (unless you switch to {$zerobasedstrings}) and for arrays you could solve that with @MyReturnStr[low(MyReturnStr)] (in case you often replace arrays with one using a different lower bound -- but in that case, other code may break too).</div><div><br></div><div><br></div><div>Jonas</div></div></body></html>
