BrainF***- is a BrainF*** derivative that has two more instructions:

Command Operation
_ Subtracts the current cell from the ce-pointer-plus-oneth cell
) Inverts the current cell, from 0 -> 1+ / 1+ -> 0.

This lets you compare chars easily:

 +++++++++++++[>+++++<-],_[{if not}])[{if}]

It also allows for else-if by subtracting, doing a linz (loop if not zero) and inverting a value.



Set the first cell to be the exit value, for example, 65.

Random program:


Get input, if it's not A, loop. Else, print A a lot of times.
