                                 Quiz 10

                               (10 points)


    Multiple-choice questions are 2 points each and true-false
    questions are 1 point each.  Other problems are worth points
    marked.  On multiple-choice questions, pick the best available
    answer.


1.  Suppose I want to use DFSORT to sort a data set in descending       
    order on a key which is in bytes 12 through 19 of each record.
    What DFSORT control statement will I need?

    A.  SORT FIELDS=(8,12,,D)
    B.  SORT FIELDS=(11,8,,D)
    C.  SORT FIELDS=(12,19,,D)
    D.  SORT FIELDS=(12,7,,D)
*** E.  SORT FIELDS=(12,8,,D)


2.  Which of these is not a DD name we need when we run DFSORT?

    A.  SORTIN
    B.  SORTOUT
*** C.  SYSPRINT
    D.  SYSIN
    E.  SORTWK01


3.  If we use an Input Procedure and an Output Procedure in a COBOL 
    Sort operation (and use no extra DFSORT control statements), then 
    the output data set must contain exactly as many records as the 
    input data set.

    A.  True
*** B.  False


4.  In COBOL sorting, we can write a record into the workspace data set
    using the Release verb.

*** A.  True
    B.  False


5.  (4 points)  In a COBOL program, we have the following in Working-
     Storage: 

       01  Item-1                      Pic 99V9  Value 43.8
       01  Item-2                      Pic XXX   Value ?TYX?.
       01  Item-3                      Pic 9V99  Value 3.14.
       01  Item-4                      Pic 99V99 Value 1.14.

     and in the Procedure Division, we have:

       Call 'SUBPROG' Using By Reference Item-1
                            By Content   Item-2
                            By Reference Item-3
                            By Content   Item-4. 

     In SUBPROG, we have a Linkage Section including:

       01  Q-1                         Pic 9V99.
       01  Q-2                         Pic XXX.
       01  Q-3                         Pic 999.
       01  Q-4                         Pic 999V9.

     and we have

       Procedure Division Using Q-1, Q-2, Q-3, Q-4.

     and later on:

       Move 7.68 to Q-1.
       Move ?CWF? to Q-2.
       Move 18.7 to Q-3.
       Move 385.6 to Q-4.

     Suppose these are the only statements in SUBPROG which change the
     values of Q-1, Q-2, Q-3 and Q-4.  What values will Item-1, Item-2, 
     Item-3 and Item-4 have after control is returned to the calling 
     program?  (Write every byte of the value.  If a decimal point is 
     involved, print a ?V?.)


         Item-1 = __76V8____           Item-2 = ___TYX____


         Item-3 = __0V18____           Item-4 = ___01V14__
