Subject: a simple Sequential_IO question

Hello Netlanders:
I personally know very little about Ada. I am sending this on
behalf of a professor who is having problems with VAX Ada. He is trying
to do simple sequential I/O in his program.
----------------------------------------------------------------------
with Sequential_Io;
use Sequential_Io;
procedure file_test is
infyle, outfyle: file_type;
var : integer;
begin
open(infyle, in_file,"input.fil");
create(outfyle,out_file,"output.fil");
while not end_of_file(infyle) loop
read(infyle,var);
write(outfyle,var);
end loop;
close(outfyle);
close(infyle);
end file_test;
----------------------------------------------------------------------
When I include "use sequential_io", the compiler keeps on telling me
that "sequential_io" is not a generic package. The professor claims
that the above program works with an Ada compiler on the PC.
I tried to instantiate the package with:
package s_io is new sequential(integer);
use s_io;
But that still won't work. Will some of you Ada gurus out there
help me with this rather simple question? A sample program with
"sequential_io" would be of great help.
Thanks in advance for any help
P.S. We are running VMS 4.5 on a VAX 8650.
