var x, y: int # declares x and y to have the type ``int``

var
  x, y: int
  # a comment can occur here too
  a, b, c: string
  

#Constants
const x = "abc" # the constant x contains the string "abc"

const
  x = 1
  # a comment can occur here too
  y = 2
  z = y + 5 # computations are possible

#Let statements - single assignment
let x = "abc" # introduces a new variable `x` and binds a value to it
x = "xyz"     # Illegal: assignment to `x`
