{{implementation|Brainf***}}
RCBF is a set of [[Brainf***]] compilers and interpreters written for Rosetta Code in a variety of languages.

Below are links to each of the versions of RCBF.

An implementation need only properly implement the following instructions:
{| class="wikitable"
!Command
!Description
|-
| style="text-align:center"| <code>&gt;</code> || Move the pointer to the right
|-
| style="text-align:center"| <code>&lt;</code> || Move the pointer to the left
|-
| style="text-align:center"| <code>+</code> || Increment the memory cell under the pointer
|-
| style="text-align:center"| <code>-</code> || Decrement the memory cell under the pointer
|-
| style="text-align:center"| <code>.</code> || Output the character signified by the cell at the pointer
|-
| style="text-align:center"| <code>,</code> || Input a character and store it in the cell at the pointer
|-
| style="text-align:center"| <code>[</code> || Jump past the matching <code>]</code> if the cell under the pointer is 0
|-
| style="text-align:center"| <code>]</code> || Jump back to the matching <code>[</code> if the cell under the pointer is nonzero
|}
Any cell size is allowed, &nbsp; EOF &nbsp;  (<u>E</u>nd-<u>O</u>-<u>F</u>ile) &nbsp; support is optional, as is whether you have bounded or unbounded memory.
