Question:
---------
can anyone tell me how i can get mystring := "4.56" to become myfloat :=
4.56
or mystring := "123" to become myinteger := 123

Answer:
--------
it easy if you know how

that's the manual

27 procedure Get(From : in String; Item : out Num; Last : out Positive);

28 Reads a real value from the beginning of the given string, following
the
same rule as the Get procedure that reads a real value from a file, but
treating the end of the string as a file terminator. Returns, in the
parameter Item, the value of type Num that corresponds to the sequence
input. Returns in Last the index value such that From(Last) is the last
character read.
 here is an example
s : string (1..10) := "1.20      ";
f : float
l : integer;

 begin
Get(From => s;,
Item => f,
 Last => l);

   Myfloat : constant Float := Float'Value (MyString);

> or mystring := "123" to become myinteger := 123

  MyInteger : constant Integer := Integer'Value (MyString);
