I have a little question I wrote a calculator in cobol, and I'm not so expert I give you here the code:
DISPLAY "CALCOLATRICE".
DISPLAY "ATTENZIONE, IL RISULTATO NON HA SEGNI!".
DISPLAY "CHE VUOI FARE?".
DISPLAY "1 ADDIZIONE".
DISPLAY "2 SOTTRAZIONE".
DISPLAY "3 MOLTIPLICAZIONE".
DISPLAY "4 DIVISIONE".
DISPLAY "5 ESCI"
ACCEPT INPUT1
IF INPUT1 = 5
DISPLAY "OK, BUON LAVORO :)"
STOP RUN
END-IF.
IF INPUT1 = 1
DISPLAY "PRIMO NUMERO"
ACCEPT A
DISPLAY "SECONDO NUMERO"
ACCEPT B
COMPUTE C= A + B
DISPLAY "Computing"
DISPLAY "Computing."
DISPLAY "Computing.."
DISPLAY "Computing..."
DISPLAY "Computing...."
DISPLAY "Computing....."
DISPLAY "Computing......"
DISPLAY A "+" B " FA..."
DISPLAY C
ELSE
IF INPUT1 = 2
DISPLAY "PRIMO NUMERO"
ACCEPT A
DISPLAY "SECONDO NUMERO"
ACCEPT B
DISPLAY "Computing"
DISPLAY "Computing."
DISPLAY "Computing.."
DISPLAY "Computing..."
DISPLAY "Computing...."
DISPLAY "Computing....."
DISPLAY "Computing......"
DISPLAY A "-" B " FA..."
COMPUTE C= A - B
DISPLAY C
ELSE
IF INPUT1 = 3
DISPLAY "PRIMO NUMERO"
ACCEPT A
DISPLAY "SECONDO NUMERO"
ACCEPT B
COMPUTE C= A * B
DISPLAY "Computing"
DISPLAY "Computing."
DISPLAY "Computing.."
DISPLAY "Computing..."
DISPLAY "Computing...."
DISPLAY "Computing....."
DISPLAY "Computing......"
DISPLAY A "x" B " FA..."
DISPLAY C
ELSE
IF INPUT1 = 4
DISPLAY "PRIMO NUMERO"
ACCEPT A
DISPLAY "SECONDO NUMERO"
ACCEPT B
COMPUTE C= A / B
DISPLAY "Computing."
DISPLAY "Computing.."
DISPLAY "Computing..."
DISPLAY "Computing...."
DISPLAY "Computing....."
DISPLAY "Computing......"
DISPLAY A ":" B " FA..."
DISPLAY C
END-IF
END-IF
END-IF
END-IF.
STOP RUN.
Now, I want to give a message saying "Do you want to do other operations?" and, if the answer is yes it returns to the beginning, and if you say no it goes to the end. If you can explain to me how, but not with paragraphs if you can. Can I have the code correct?
