Execute HQ9+/Ursala is part of RCHQ9+. You may find other members of RCHQ9+ at Category:RCHQ9+.
Execute HQ9+/Ursala is an implementation of HQ9+.
Other implementations of HQ9+.
In this Ursala program, there are the following constraints:
- Unrecognized operators or a missing input file cause diagnostic messages.
- Since the accumulator is unreadable and has no operational consequences, its value isn't stored.
- A line break at the end of the file, if any, is ignored.
#import std

Take one down and pass it around, -[quantity "n"]- on the wall.]-

No more bottles of beer on the wall, -[quantity 0]-.
Go to the store and buy some more, -[quantity "n"]- on the wall.]-
