PURE procedures

PURE procedures

The purpose of PURE procedures is to allow a processor to know when it is safe to implement a section of code as a parallel operation. The freedom from side effects of a pure function assists the efficient implementation of concurrent execution and allows the function to be invoked concurrently in a FORALL without such undesirable consequences as nondeterminism. It also forces some error checking on functions used in a FORALL construct.
