The rules of operator precedence are complicated and can lead to errors. For this reason, parentheses should be used for clarification in complex
statements.
This rule raises an issue when more than the allowed number of non-like operators are used in a statement without parentheses to make execution
order explicit.
Noncompliant code example
With the default threshold of 2:
COMPUTE WSRESULT = WS1 + 5 * WS2 - WS3**2 END-COMPUTE *> Noncompliant
COMPUTE WSRESULT2 = WS1 + 5 + WS2 + WS3 + WS4 END-COMPUTE
Compliant solution
COMPUTE WSRESULT = WS1 + (5 * WS2) - (WS3**2) END-COMPUTE
COMPUTE WSRESULT2 = WS1 + 5 + WS2 + WS3 + WS4 END-COMPUTE
