First Hour Exam



Name 
_____________________________


















Friday, Sept. 27
100 pts.

I.	(15 pts.)	Name the four divisions of a COBOL program, giving 
a brief description of each.



II.	(15 pts.)	A local performing group needs to keep track of 
volunteers for productions.  Records in the file have the 
following organization:

Volunteer-record

	Volunteer name, consisting of
		last name (15 characters alphanumeric)
		first name (15 characters alphanumeric)
	Volunteer birthdate, consisting of
		Month (2 character numeric)
		Day (2 character numeric)
		Year (4 character numeric)
	Production, consisting of
		Fall/Spring/Winter code (2 characters alphanumeric)
		Year (4 characters numeric)

	Given these facts, write a complete COBOL record description 
for this record.  Note that the record consists of three 
subfields which are further divided.







III.	(10 pts.)	Suppose that we have the following:

01	STUFF.
	02	FLD-A	PIC X(3) VALUE "123456789".
	02	FLD-B	PIC X(10).
	02	FLD-C	PIC X(10) JUSTIFIED RIGHT.
	02	FLD-D	PIC XXXBXX/XXXX.

	What would be the effect of the following MOVE statements?  
Be sure to indicate any spaces by using a check mark.

	MOVE FLD-A TO FLD-B.	FLD-B = _______________

	MOVE FLD-A TO FLD-C.	FLD-C = _______________

	MOVE FLD-A TO FLD-D.	FLD-D = _______________



IV.	(15 pts.)	Suppose that we have the following:

01	SOURCE-FIELDS.
	02	SRC-C	PIC S9(5)V99	VALUE 12345.67.
	02	SRC-D	PIC S9(5)V99	VALUE -12345.67.
	02	SRC-E	PIC S9(5)V99	VALUE 0.03.
01	TARGET-FIELDS.
	02	DST-A	PIC $$$$,$$$,$$$.$$CR.
	02	DST-B	PIC $***,***,***.**.
	02	DST-C 	PIC $$,$$9.99.

	What would be the effect of the following MOVE statements?  
Be sure to indicate any spaces by using a check mark.

	MOVE	SRC-C	TO	DST-A.     DSC-A = 
__________________
		
	MOVE	SRC-C	TO	DST-B.     DSC-B = 
__________________
		
	MOVE	SRC-D	TO	DST-A.     DSC-A = 
__________________

	MOVE	SRC-E	TO	DST-C.     DSC-C = 
__________________
		
	MOVE	SRC-C	TO	DST-C.     DSC-C = 
__________________
		(be careful with this last one!)


V.	(10 pts.)	The variable TOTAL-SALES contains the total sales 
for a salesperson.  If TOTAL-SALES is less than $10,000, then 
the salesperson's commission (COMMISSION) is 10% of the 
TOTAL-SALES.  Otherwise, the COMMISSION is $1,000 plus 25% 
of the amount of TOTAL-SALES in excess of $10,000.

	Write the COBOL statement necessary to compute the 
salesperson's COMMISSION.


VI.	(35 pts.)	On this and the following pages, write a complete 
COBOL program which will read records described in problem II 
(the VOLUNTEER-REC question) and which will print a report 
with one line for each volunteer, printing the volunteer's full 
name and birthdate.  No headers or footers are required for this 
exercise.


a.	(5 pts.)	Write the IDENTIFICATION DIVISION entries for this 
question.









b.	(10 pts.)	Write the ENVIRONMENT DIVISION entries for this 
question.


c.	(10 pts.)	Write the DATA DIVISION entries for this question.  
Please note that no headers and footers are required, and the 
file description has already been written in problem #2 - in 
the following you do not need to write it down again, but 
simply put a note where it belongs.  The FD and WORKING-
STORAGE entries should, however, go here.

d.	(10 pts.)	Finally, write the PROCEDURE DIVISION entries for 
this question.  No documentation is necessary.
