2. Explain to the customer that if he received "code patches", they
may not be included on the new card.
Note: The host attachment card has a code patch if a " * "
appears in the code level on the first page of the Host print test.
The IPDS card has a code patch if a " * " appears in the code
level on the second page. (A higher level of code without a " * "
probably incorporates the code patch.)
