[Scott Malcolm Smedley]

How can I "print" an array of integers/characters/strings etc
in ADA?? I mean "print" as in Printer.

For example, let's say I had an array(1..10) of integers.
How could I print each integer one underneath the other on
a printer?

I'm not 2 sure whether it matters or not, but I am using ADA on
a DOS machine, not UNIX.

Thanks 4 any help U can give...

The Meridian Ada compiler manual has the following information...

-----start-quote--------------------------
Special file names
Note that there are special file names that refer to
non-disk devices

CON\x7f - the console
AUX - serial port1
...
LPT1 - parallel port 1
PRN - same as LPT1
...

To open one of the special file names for output, use
create with mode out_file as in the following example.

with text_io;	use text_io;
procedure printer_demo is
	f:file_type;
	printer:constant string := "PRN";
begin
	create(file => f, name => printer);
	put_line(f, "this is a test");
	new_page(f);
	close(f);
end printer_demo;
-------------------------------------------

Your mileage may vary depending upon what networks you are
attached to.

Open the printer as a sequential file...  (There's probably a better way
of doing it, but this works.)

with SEQUENTIAL_IO;
procedure FOO is

  package LPT_FLOAT_IO is new SEQUENTIAL_IO(FLOAT);  -- You need one of these
  use     LPT_FLOAT_IO;                              -- for each type you use.

  PRINTER: FILE_TYPE;
  STUFF: array(1 .. 10) of FLOAT;
  PRINTER_DEVICE: STRING(1 .. 20);

begin -- FOO

  PRINTER_DEVICE:="lpt1";               -- DOS uses LPTx, UNIX uses /dev/lptx.
  OPEN(PRINTER, OUT_FILE, PRINTER_DEVICE);

  -- Fill your array.

  WRITE(PRINTER, STUFF(1));

end FOO;
