WHEN MARKS >= 60 AND MARKS < MOVE ‘C’ TO GRADE
WHEN MARKS >= 55 AND MARKS < MOVE ‘D’ TO GRADE

53. CASE Statements EVALUATE GRADE WHEN ‘A’ DISPLAY ‘WONDERFUL!!!!’
WHEN ‘B’ DISPLAY ‘GREAT!!!’
WHEN ‘C’ DISPLAY ‘NEED ANY HELP?’
WHEN ‘D’ DISPLAY ‘COME AND SEE ME!’
WHEN ‘F’ DISPLAY ‘SEE YOU NEXT SEMESTER’
WHEN OTHER DISPLAY ‘WE HAVE A PROBLEM!’
END-EVALUATE.

54. Problem
ANNAME is a 20 character field in the file, ANMPF that stores an animal name.
ANMPF is a Physical file that contains a record for each of animals clients at the Seneca Vet Clinic.
You are required to write a COBOL program that selects all of the animals listed in ANMPF that start with a C.
What COBOL statement would select all of the animals names that start with the letter ‘C’.

55. System Date
Function current-date
Function convert-date-time

56. Indicators in Display Files

57. Option Indicators in COBOL
Binary Values
Working Storage Definition example
01 ws-indicator-list.
05 IN88 INDICATOR 88 PIC 1 value B’0’.
Passed to display files in the write statement
Write Display-record
format is ‘RECORD1’
indicators are ws-indicator-list.

58. Example – Indicator 90 displays the message, Employee Name is invalid
Working Storage.
01 ws-indicators.
05 IN90 INDICATOR 90 pic 1.
Procedure Division.
If scr-employee-name is equal to spaces
move b’1’ to IN90
else
move b’0’ to IN90
end-if.

59. Response Indicators in COBOL
Stored as binary values in the display file and passed as PIC X(2) via the control Area.
Select Display-file
assign to workstation-dspfile-si
organization is transaction
control area is ws-control.
Working Storage Section.
01 ws-control.
05 ws-function-key pic x(2).

60. Example – check to see if function key 3 was pressed.
Select Display-file
assign to workstation-dspfile-si
organization is transaction
control area is ws-control.
Working Storage Section.
01 ws-control.
05 ws-function-key pic x(2).
Procedure Division.
if ws-function-key = ’03’
…..
end-if.

61. Display file ‘Both’ Fields
Input and Output buffers
REDEFINES clause
Different data specifications for same memory location
Screens with both fields need an input and an output buffer.
