File I\O

File I\O

[Gavin Bowra]

Hi
   I need a bit of a pointer on File I\Os Basically I have to create and
read a file. My problem is that I can't get a handle on how it is done, I
have the LRM and Rendezvous with Ada 95 but I can't follow the explanation
or example ( I must be thick or something ;-) ) If there is anybody out
there who can explain this to an IDIOT so he can understand would be greatly
appreciated.

Hi,
    Text file required....but saved to A:\.

procedure create (file: in out  File_type
                             mode: in     File_mode := out_file;
                             name: in      String        :=  "   ";
                             form:  in      String        :=  "   ");


Last night I was trying to get this to work, if you could maybe point out
ifthis will work.

      Procedure File_Buy  is
      Sponsors : File_Type;

      Begin --File_Buy

      New_Line(2);
      Put("                Please enter the file name");


      Create(In_Sponsors, Out_File, "A:\Sponsors.dat");

      Close (Sponsors);

      End File_Buy;

There are some examples on http://www.AdaPower.com/ under the "Source
Code" section.  If you still have problems post your source code, with
details of the environment you are using it in, and a description of the
specific problem.

On my web page (http://www.mcondic.com/) under Ada Programming, you can
find a bunch of small programs called "GNAT Esamples". I used these to
teach an intro to Ada level in-house class. There are a few small, self
contained programs in that set which cover various forms of File IO.
They should all compile and run successfully. If not, send me an e-mail.
