An ABL application can also contain non-executable comments. There are two styles of comments, single-line and multi-line. Single-line comments begin with // and stop at the end of the line. Multi-line comments begin with /* and end with */. This type of comment can wrap over multiple lines or be on a single line. The following example shows both comment styles:
/* Step through all customers with a balance under 1000 */

FOR EACH Customer NO-LOCK WHERE Customer.Balance < 1000:
  DISPLAY Customer.Name.
  FOR EACH Order OF Customer NO-LOCK:
    DISPLAY Order.OrderDate.    // Display order dates of each customer
  END.
END.
