I was wondering if there was a program out there that could translate a
program written in Qbasic (gorilla.bas) into Pascal?  I would appreciate
any responce.

Thank You

Hi,

The idea of translating QBasic into Pascal already came to my mind,
but I gave up. I was attempting to translate the program manually and it's
rather difficult.

I don't know if anyone out there has already written a program to translate
QBasic into Pascal, but I know it's not very easy.

Problems :

1) QBasic (as any other BASIC language) can use variables which have not been
declared. The translator must built the declarations itself. Difficult but
possible. (So the BASIC program must be read twice : once for retrieving the
variables, and once again for the translation.)

2) The GOSUB statement is a typically BASIC statement and can't easily be
translated into another language. (They use procedures instead.)
Well, GOTO exists in Pascal, but it's advised to avoid using it, since you
can do most of things another way.

If no program exists to translate QBasic into Pascal, you will have to do
it yourself ! If you're patient and have time to do it...  Good luck !

Bye.

Christophe.

Do you think he would care? I think he has better things to worry about.
Also I do not see anything wrong in converting a program.

Is that some problem?

Gosub is basically same as call in assembler, so it is very easy to
emulate:

Program Lets_eat_spaghetti;

label sub;

Begin
   Write('Going sub for the first time ..');
   asm call sub end;

   Write('Going sub for the second time ..');
   asm call sub end;

   Writeln('Exiting program');
   halt;

sub:

   Writeln(' Returning from the subroutine');
   asm ret end;

End.

Turbo Pascal manual says that one cannot touch SP, but I think that
does not apply if you restore the value before the procedure exits.

Still, it's a matter of principle.  Oh, wait a minute...we're talking about
Microsoft...

Anyway, translating a program is not a copyright violation unless you intend
to sell it, give it away, or otherwise let someone else have it.  Just like a
book.  If you have an original Russian copy of War and Peace and want to sit
down and translate it into English so your 8 year old son can read it, the
Tolstoi estate is not going to come after you.

Besides, the original posting was about how to convert QBasic code into
pascal...not really about any particular program...I think gorilla.bas was
just an example.  And why would anyone want to have a gorilla.pas?

Just waiting around for yesterday..

Well, I always thought that gorilla.bas was one of the undocumented
treasures of DOS 5, so a Pascal version would be just fine.

Two oversized monkeys throwing exploding bananas at each other--
what could be better than that?

Yes, but a snakes.pas now...

A version supporting network play?

Anyway, I think it's better to rewrite the darn thing from scratch, and
use gorilla.bas as a reference for various problems, like drawing or
calculating the path of the banana (or whatever the original poster feel
is a problem).

Hey, you by any chance didn't start work on this did you?

: I don't know if anyone out there has already written a program to translate
: QBasic into Pascal, but I know it's not very easy.

: Problems :

: 1) QBasic (as any other BASIC language) can use variables which have not been
: declared. The translator must built the declarations itself. Difficult but
: possible. (So the BASIC program must be read twice : once for retrieving the
: variables, and once again for the translation.)

Nope.   You can set up a table for variables, reserve some space and fill
it up as you go along.

: 2) The GOSUB statement is a typically BASIC statement and can't easily be
: translated into another language. (They use procedures instead.)

Ummmm, procedure/function calls are almost equivalent of GOSUB / RETURN.
