Hello!

Well, that statement will only work if BUF and the string Get_Line returns both
have the same length...
One way to solve this problem is to use a declare-block, ie not declaring BUF
until you know how large it needs to be:

declare
  BUF : String := Get_Line(Incoming_Socket);
begin
  -- Do stuff that uses BUF.

end;

Another way is to process the data in a procedure or function:

procedure Do_Stuff (BUF : String) is ...

And in your program you call it with Get_Line as a parameter:

...
Do_Stuff (BUF => Get_Line (Incoming_Socket));
...
