Explanation

In PL/SQL, <> and >> are used to define label delimiters, which mark named blocks for use with GOTO statements or to label loops for nested loop control. The << marks the start of a label and >> marks the end. This is distinct from comment markers (-- or /* */) or comparison operators like >= or !=.
