Reserved words

The identifiers listed in Table 1 are reserved words and their usage is strictly limited. Here are some examples where they cannot be used:

• As variable names
  global := 55 // doesn't work!

• As key in static dictionary expressions
  X := dict // doesn't work!

• As thread id in par_start
par_start<global>: tuple_div(3, 2, Out) // doesn't work!
