The Sugar Exporter Co-operative works in a
distributed environment, as they are associated with a number of
plants situated all across India. On receiving an export order, the
Co-operative distributes the order to some of its plants. Assume
that there are only three plants and that all these plants keep
records of their production in COBOL in the following format
: |
|
|
| Sugar Quality |
2 digits |
| Quantity |
5 numeric digits
|
| Export Order No. |
6 alphabets
|
| Order Date |
8 digits |
| Date of Completion of Order |
8 digits
|
|
|
|
Write a program in
COBOL which merges the data from these three plants to one single
master file. |
|
|
please notice :
(i). The files received
from the plants are sorted on the field "Date of Completion of
Order". (ii). The master file (which is to be generated )
is sorted on the field "Order Date".
(iii). The date
of completion of order in the single master file will be the highest
of the date of completion received from plants.

ABC Bank keeps
accounts of its customer using a COBOL program. The structure of
their master file is : |
|
|
| Account
Type
|
2 characters |
| Account Number |
5 numeric digits
|
| Name |
25 characters |
| Address |
50 characters |
| Balance |
6 characters
|
| Last withdrawn on |
8
digits. | |
|
|
This master file is used
for daily transactions of the customers. Every time a customer
withdraws money his master should be updated. Write a program in
COBOL for updating the master file on customer withdrawals on-line.
Indicate the file organisation you have chosen. Give reasons for
doing so. |

(a). |
Write a
program in COBOL for printing Fahrenheit equivalent of Celsius
temperature in the range of 0 to 1500 F at 100 interval. The
conversion formula to be used is : |
|
|
0 Celsius = 5/9 (0
Fahrenheit -- 32) |
|
(b). |
Identify the
error/errors, if any, in the following COBOL statements. Give
reasons. |
|
|
(i). PERFORM PARA_X
UNTIL CTR=8
PARA_X
ADD X
TO Y.
ADD 1
TO CTR.
IF CTR = 8
STOP

(ii). IF A = 5 OR IF A = 8
PERFORM.PARA_II
END_IF.
(iii) ADD X, Y, Z GIVING
A ROUNDED
ON
SIZE ERROR MOVE BLANK TO C.
(iv). MOVE AMT1 TO
1000.
MOVE 'ABC', AMT2 TO AMT3
(v). PERFORM PARA_Z THRU
PARAC
VARYING X1 FROM 1 UNTIL X1 < 100.
