# 99 bottles of pain

99 bottles of pain is an esoteric programming language by User:BoundedBeans with the syntax based around the output of a common programming problem.

To start, each verse of the song is given a number. It must go down by 1 every verse, but it may start at any number, not just 99, and it may also end at any number, not just 1. A blank line is also required between verses, and will not be interpreted as a subroutine.

Each verse in the song goes like this:

(verse number) bottles of b(x1)r on the wall (verse number) bottles of b(x2)r Take (x3) down Pass it around (verse number) bottles of b(x4)r (operator) on the wall.

So we have 5 arguments to each verse: x1, x2, x3, x4, operator. All operators are quadary, a.k.a. they accept 4 arguments always.

x1, x2, and x4 have a binary sequence assigned to them, while x3 has a decimal representation of the integer. Note that the binary sequence should always begin with 1, and the decimal should follow this rule as well. x1, x2, x3, and x4 are not direct numbers, but instead each index a variable (multiple can refer to the same variable in a verse). Operations are performed between these variables based on the word before " on the wall". The result is always stored in x4, except for "set" which also stores a result in x2, and "put" which stores a value in all of its arguments.

e - 0 E - 1

## Operators

Put these operators before " on the wall".

"put": Declare the 4 values and initialize them all as 1. If they already exist, throw an error. "placed": Add the 4 values together and store the result in x4. "sitting": Do (x1 - x2) - (x3 - x4), store the result in x4. "laying": Multiply the 4 values together and store the result in x4. "lying": Do (x1 / x2) / (x3 / x4), store the result in x4. "unnoticed": Do (x1 % x2) - (x3 * x4), store the result in x4 "set": Set x2 to x1, set x4 to x3 nothing: no-op, but can still check x4 for a loop.

But there are some extra things allowing even more functionality.

The first is that the "Pass" in "Pass it around" can contain an extra 's'. This causes it to print x4 as an ascii value if negative, and as a number if positive. To print negative numbers, just print a hyphen first.

The second is that the "Take" in "Take one down" can have a lowercase 't'. This causes it to accept input into x3 before performing the calculation, and keeping this value in x3 after it's done.

Finally, while loops can be implemented by adding a space before some verses. Whatever verse is directly above the indented code will run that code if and only if x4 is greater than 0 after the calculation, and will loop as long as x4 continues to be greater than 0. Also, these can be nested, by including more spaces, and they also have a separate verse number, so make sure to remember to not skip numbers outside of it, or the code will break. Note that current x4 does not stay checking for 0, the one checked for 0 is the x4 of the last statement in the loop.

Hello world: (I suspect I may have made a mistake somewhere here, but this was painful to write and I don't want to check it for errors)
