Blarb is designed to be the simplest possible (esoteric) systems programming language. Being as such, there is only one logical operator: NAND. It is an assembly-like, stack & register based language.

Example for creating an "add" function
; Pushes the current line to the stack ; The stack will now contain 2, 3, and the current line number ; No token are allowed after a call to a label 2 3 0$andi 0 0 0 0 0 0 60 % ; exit by calling syscall 60 ; Bitwise AND the two arguments and push the result to the stack #andi 4 3 ! ; A NAND B (the two arguments) 4 4 ! ; NAND the result with itself to bitwise NOT it ; Pop the stack frame and second argument. ; The remaining stack data will only include the return value ; The "2 0 ~" sets the line pointer to the return address ; The "2 ^" pops the return address and the second argument 2 0 ~ 2 ^ ; Run this program with "--debug" to see the result on the stack
