Ist das slash-Zeichen in einer Oracle-PL/SQL-Skript einen Fehler?

Ich bin der Sortierung eine Reihe von SQL-Skripten für meine Firma geschrieben in Oracle PL/SQL. Ich kam über eine wesentliche Skript mit einem seltsam platziert Schrägstrich in der Nähe der Unterseite. Es wird geprüft, in CVS diese Weise. Ist dies eine Reine syntax-Fehler oder ist es eine Funktion zu haben ich bin mir nicht bewusst. Die etwas verwirrenden Drehbuch:

set serveroutput on size 2000;
--PL/SQL block to link ISSN in serial base on a company's ISSN text file

cursor ItemCursor is
select issn is2 from web.obfuscated1 where issn is not null
