Ville Saalo This appears to assume an A4 sheet. It doesn't fit in a letter sized page. Otherwise it works great!

Volker Beyler Hi Ville,

this is correct. As A4 sheets are common in my place, I used those.
If you exchange the line
99 bottles 8 mul 20 add moveto
with the line
99 bottles 7 mul 20 add moveto
it works fine on letter format, too.

Thanks for the feedback!

Rüdiger Kupper I like your comment on "buying" the beer instead of defining it. Good style.
