== Why is this an issue?

Call stacks containing lot of ``++PERFORM++`` statements is a key ingredient for making what's known as "Spaghetti code".

Such code is hard to read, refactor and therefore maintain.


This rule supports both sections and paragraphs. 


=== Noncompliant code example

With a threshold of 3:

[source,cobol]
----

FIRST.
  PERFORM SECOND.

SECOND.
  PERFORM THIRD.

THIRD.
