Sharp flat

The title of this article is not correct because of technical limitations. The correct title is actually #b.

#b is a Brainfuck-equivalent esolang created by User:None1.

Why is it named #b

In music, there are two signs, sharp (#) and flat (b). # has an odd ASCII value, while b has an even ASCII value, that's the trick.

In #b, all characters with an odd ASCII value is treated as #, and all characters (except line feed) with an even ASCII value is treated as b.

Execution

Every character (except line feed) in a #b program can be treated as # and b, and Brainfuck has 8 opcodes. Because 2**3=8, three characters make a brainfuck opcode, remaining characters are ignored.

Here is the #b to Brainfuck conversion table:

#b   Brainfuck
bbb  +
bb#  >
b#b  ,
#bb  [
b##  ]
#b#  .
##b  <
###  -
