Defining Variables

Use name = value to create or update an untyped variable.

variable = 10

Top-level variables are global and can be read inside functions:

greeting = "hello"

def showGreeting() (
  log greeting
)

showGreeting()
// hello

Inside a function or block, declare local variables with a type keyword or auto. Local variables shadow globals with the same name and do not leak out of the function.

any count = 1

def increment() (
  any count = 10
  count += 1
  log count
)

increment()
log count
// 11
// 1

Variables must be assigned or declared before they are read. Referencing an undefined variable is an error in current OSL.
