Re: Newbe compile problems

Jamie asks about another plainly illegal program

 with Float_Text_IO;
 use Float_Text_IO;
 procedure Think is
   A, B : Float := 0.0; -- A and B initially zero; note the period.
   I, J : Integer := 1;
 begin
   A := B + 7.0;
   I := J * 3;
   B := Float(I) + A;
   Put(B);
 end Think;

Certainly you cannot expect GNAT or any other compiler to compile this
if you do not supply the package Float_Text_IO (there is no standard
package of this name).

You need to get a text book that clearly decsribes Ada 95, and thus
corresponds with the compiler you are using (which is GNAT in this case).

In general people seem to make a lot of trouble for themselves by not
having a coherent and relevant text and documentation. In the case of GNAT,
you need an Ada 95 text book and gnatinfo.txt (or with GNAT v3.07, the
GNAT manuals).
