Nesting too many control flow statements (such as ``++IF++``, ``++PERFORM++``, ``++EVALUATE++``...) should be avoided as it makes the code complex and therefore difficult to maintain.

== Noncompliant Code Example

With a threshold (maximum allowed control flow statement nesting depth) of 3:

----
IF A = 1
    PERFORM 
        MOVE A TO B
        PERFORM
            IF B = 1 *> Noncompliant
              MOVE "HI" TO S1  
            END-IF
        END-PERFORM
    END-PERFORM
END-IF.
