The use of parentheses, even those not required to enforce a desired order of operations, can clarify the intent behind a piece of code. But
redundant pairs of parentheses could be misleading, and should be removed.
Noncompliant code example
COMPUTE x = (y / 2 + 1). *> Compliant even if the parenthesis are ignored by the compiler
COMPUTE y = 2 * ((x + 1)). *> Noncompliant
Compliant solution
COMPUTE x = (y / 2 + 1).
COMPUTE y = 2 * (x + 1).
