I don't have a 1st edition Unix, nor any later 1, but...

DOES THIS WORK ?

It looks like "1 bottles" and "0 bottle" to me,
although it will "break" before it ever uses "0 bottle" !

And does "auto a" start at 99 ?
/* Is 99 snatched from within the comment ? */

It would probably be better if this program would not be
completed within one day.

I found it when there were only 997 variations of
99-bottles-of-beer. Somehow Oliver Shade suddenly counted
1000 without any new additions. There must be a lot of
beer involved here...

But not in B : When the one-thousand celebrations reach
a high there is no replenishing by "going to the store" !

Nonetheless, congratulations with 1000, I like this site !

P.S. For a clear description of full 99-logic see the
dedicated intermediate language in my DEBUG version of 99.
It could be implemented with any Turing-complete language
although mine is not.

Sorry about forgetting the line a = 99;, which initializes the variable; my mistake. The correct code reads:

/* 99 Bottles of Beer
B Version
By Pietro Gagliardi
Started and Completed August 21, 2006

main()
{
auto a;
a = 99;

while (a >= 0) {
printf("%d %s of beer on the wall!*n", a, (a == 0 ? "bottle" : "bottles");
printf("%d %s of beer,*n", a, (a == 0 ? "bottle" : "bottles");
printf("You take one down, pass it around,*n";
if (a == 0) break;
printf("%d bottles of beer on the wall!*n*n", --a);
}

printf("No more bottles of beer on the wall!*n";
}

It's been almost thee years and I don't really know B, but if that's an arithmetic if then the first commenter was right: that code will print "1 bottles".
