Hi,

Another Newbie question.  I"m having trouble understanding concatenation in
Ada with its unbounded strings, and the difference between Character arrays
and String arrays.

If I concatenate two Bounded Strings

S:String(1..4):="ABCD";
T:String(1..2):="EF";
U:String(1..N);
Begin
    U(1..6):=S&T;     --Constraint Error!! Why?
or...
    U:=S&T;   ---Constraint Error!  Why?

    Put(U);
end;
Also If I have an array of Characters

Chars:array range(1..3) of Characters:=('a','b','c');

How can I convert it to a string?

Put(Chars) --Compile Error:Invalid param list!

I look forward to getting answers to these pesky problems.

Thanks as always,

Justin
