== introducting students to programming. Blue, as of 1998,
== has been discontinued and the source code for compiler
== and IDE put up for grabs at:

== This is a very minimal example since I haven't read much on the language
class BottlesOfBeer is
uses -- No other classes to use, just the auto-included System class
internal
== Define internal variables and routines here, but for this example,
== there is none needed.
interface
creation is
== This is the typical class constructor. Had there been parameters,
== the signature would have taken this form:
==
== creation (param: Type) is
do
-- nothing to do...
end creation
routines
countdown is
var
count: Integer
done: Boolean
do
loop
print (count, " bottles of beer on the wall,\n")
print (count, " bottles of beer,\n")
print ("Take one down, pass it around,\n")
count := count - 1
if count <= 0 then
print ("No more bottles of beer on the wall.\n")
done := true
else if count = 1 then
print ("One more bottle of beer on the wall.\n")
else
print (count, " more bottles of beer on the wall.\n")
end if
exit on done
end loop
end countdown
end class
