  • > (greater than)
    • if 2 > 1 print hello -> hello

• 3 operands

  • + (addition)
    • if 2 + 2 4 print hello -> hello
  • - (subtraction)
    • if 5 - 2 3 print hello -> hello
  • * (multiplication)
    • if 2 * 3 6 print hello -> hello
  • / (true division)
    • if 5 / 2 2.5 print hello -> hello
  • ^ (power)
    • if 2 ^ 3 8 print hello -> hello
  • % (modulus)
    • if 5 % 2 1 print hello -> hello
  • // (floor division)
    • if 5 // 2 2 print hello -> hello

Examples

# prints "hello world"
print hello world

# repeats until var0 is 10
varlist 1
var0 0
if var0 10 end
print var0
var0 +
goto 4

# prints decimal representation of var0
varlist 3
var0 1001101
var1 0
var2 1
if var0 0 goto 11
var1 + ((var0 % 10) * var2)
var2 * 2
var0 // 10
goto 6
print var1
