NB

NB is an esolang invented by User:None1, that uses only 2 non-whitespace characters: N and B.

It is case-insensitive.

Syntax

Number constant

NB uses unary for number constants, but instead of zeros or ones, NB is used:

NBNBNBNBNB

represents 5

Output

N <value>

ASCII character output.

NBN <value>

Integer output.

Variable

Variables must have only N's and B's, too.

Variables must start with NN:

NNNBNBN

and

NN

are valid, but:

BBNBBN

is not.

Input

B <variable>

ASCII input.

BNB <variable>

Integer input.

Loops

NB has only one kind of loop: while loop, its syntax is like this:

BB <value>
<cod>
BN

Conditionals

NB has conditionals, too:

NBB <value>
<cod>
BNB

If value is nonzero, execute cod.

NBB <value>
<code1>
BNN
<code2>
BBB

If value is nonzero, execute code1, otherwise code2.

Arithmetic

<variable> BBBB <value>

Addition, adds value to variable

<variable> BBBBB <value>

Subtraction

<variable> BBBBBB <value>

Multiplication
