Hi Rikki,
Thank you very much, I tired the above code and it is
working, so another help on the same topic.
IF my function (First) of below type when who do we define the
Mid function
Array!(Tuple!(string, string)) First(string Ftext)
Tried the below but no luck
void mid(Array!(Tuple!(string, string)) function(string) func,
string mtext) {
func(mtext);
}
Looks valid.
mid(&First, "Str");
So error + full source please.
