Re: Why can't i get an EXE!

[Phoenix.]

    Tankyou very much for your assistance with my program. Your advise has
solved my primary problem. However I appear to have a new problem.
    My program now runs however it doesn't perform it's desired task. Which
is to allow the user to add and remove items from a queue and also to show
what is in the queue. This is where my problem occured when I was trying to
show what is stored within the queue.
    The problem is that as soon as the procedure ends, it appears to clear
what is stored within the que. Therefore I think the problem is that the
variables are not declared globally, and are local to each procedure, and
thus I was wondering how I declare them Globally if that is the problem.
However if it is not the problem I was wondering what the problem is.

Do not use "in out" when you are not supposed to change any of the
values in your procedure.

procedure Show(Q: in Queue; Head: in Integer; Tail: in Integer)

    Thankyou duely noted and corrected. However I am still having the same

is reset.

Package: QUE PACKAGE

Hi
I am a university student studying computer science's and have to create a

The program below compiles perfectly and builds in ADAGIDE GNAT3.11,
however, I can not get it to create the .C and .EXE files... am I making
some small fundemental mistake.

any help gladly recievied.

Yes you must make a file that contains the main procedure. Move to this
procedure the code you have put in que.adb (see below). You will have to
with and use your que package too.

Hi, what has to go into this other file, as i created a file called
main.adb, containing
use que;
and the code below.
however it asks for a main.ads file. and I am unsure what goes in here, as
if i put the procedure declarations, it will not compile.
thanks for the help...

main.adb should look like this: (you do not need main.ads)

with que; use que;

      Put_Line("   3). Quit queue program");
      Put_Line("****************************");
      get(A);

Remove the 4 lines above. You don't need them.

Move line above to add procedure.

Move line above to main procedure.

replace "in out" with "in" in the 1 line above.

This must be wrong?

Why do you do this?

This must be wrong?

When you put the initialiser inside the loop it will be called each time
and thus reset your queue. Move it outside the loop.

Yes. You have left doing your homework till the very last minute. It is due
in tomorrow - and by the looks of things, you are in a lot of trouble!

    actually I've been to all but one lecture and I think you've only turned
up for two. But you didn't really miss much.

P.S

    DON'T LIE. If you don't turn up don't assume that someone else hasn't.
And I actually started this back on the 19th Dec I just had a couple of
probs with my version and I've already spoken to the lecture to check to see
if my alternative approach is acceptable. Oh yeah where were you for todays
lecture by the way???

No need to apologise on my behalf, the group know what I'm like from my
posts. By the way, I haven't sent any emails.

Just chill, dude. Relax and don't get so wound up!

Whenever you started it is irrelevant! I'm just joking with you!

You will find that I've posted you a very informative post further down the

Array 1..500? Big time efficiency waste !!!

You have to incorporate this using linked lists.

Okay. In reference to Real Time Programming - you have to justify these
changes to the master spec.

You have implemented this using an array. The node should contain a pointer
of type link which points to the base value of the next node. Geddit?

Also - you have to:

Present a Package Spec
Present a Package Body
Present a Test Harness

Okay? So name your package body and spec the same (bar the extension), then
create a main body and include the other files in this body. Put your main
