Var=Bar

Var=Bar is an esoteric programming language by User:A, and is made up entirely of variables. Each line is just a case-sensitive variable name, followed by =, and then the variable's case-sensitive value.

The variable names can be anything including special names, and the values can be anything as well, and can also be special values:

1N	prints the variable's value.
0UT	inputs a value for the variable to take. Be careful: that 0 is zero.
+(add) -(subtract)	do math. For example: x=4 J=x - 2 sets x as value 4 and J as value 2 (4-2). Also: f=n p=o s=f + p sets f as value n(Any value without 0-9 is a string), p as value o, and s as value no (word math only works with +).
x=condition	starts a while loop named x with the given condition.
x=STOP	signifies the end of while loop called x.

Conditions have three parts, two compared values referenced by their names and a comparison. They only use 3 instructions, which can be:

>	is greater than
<	is less than
==	equal to

Example

Truth-machine

v=1N
v=0UT
x=v==1
v=0UT
x=STOP

Cat Program

Below follows the implementation of an infinitely repeating cat program:

infiniteLoop = 1 == 1
input = 1N
input = 0UT
infiniteLoop = STOP
