1.

Write the COBOL statement to add three numbers (NUM1, NUM2, NUM3) and store the answer in RSLT-WS.

2.

Referring to #1, if NUM1 has a PIC of 9(5) and NUM2 has a PIC of 9(4) and NUM3 has a PIC of 999, what PIC should be set up for RSLT-WS?

3.

Write the COBOL statement to subtract NUM2 from NUM1 and store the answer in ANS-WS.

4.

Referring to #3, if NUM2 has a PIC of 9(4) and NUM1 has a PIC of 9(5) and the result has the possibility of becoming negative, what PIC should be set up for ANS-WS?

5.

Write the COBOL ADD and MULTIPLY statement to accomplish the following: add FLD1 and FLD 2 together and store the answer in RSLT-WS. Then multiply the answer by 90% and put the answer back in RSLT-WS.

6.

Redo #5, but store the result of the multiply in RSLT-2-WS.

7.

Write the COBOL COMPUTE statement to do #6.

8.

Write the COBOL COMPUTE statement to do the following: multiply the sum of FLD1 and FLD2 by FLD3 and divide the result by FLD4. Store the answer in ANS-WS.

9.

Write the COBOL COMPUTE statement to do the following:

FLD3+FLD4

The answer should be stored in RSLT-WS.

10.

Write the COBOL COMPUTE statement to do the following:

(FLD4-FLD5)(FLD6-50)

The answer should be stored in ANS-WS.
