String Question

When using a plain String I'm getting this warning warning: missing string capacity -- assuming 255 Getting rid of this warning for Var's is not a problem as I just do: mystring : String (some number); But how do you get rid of the warning when a function returns a string such as this: function foobar( test : Integer): String; I have tried to add a capacity argument to String but then I get this error: parse error before '(' So the question is how can you assign the capacity to a String type when you are returning it from a function? I would prefer to not have to make a type for this if possible. Also while on the subject of strings are gpc strings protected against buffer overruns? Thanks Richard Jackson
