SELECT PRINT-FILE ASSIGN TO PRINTER. DATA DIVISION. FILE SECTION. FD INS-FILE DATA RECORD IS INS-REC. 01 INS-REC. 05 IDNO PIC XXXX. 05 NAMZ PIC X(20). 05 TYPZ PIC X. 88 TYPE-LIFE VALUE "L". 88 TYPE-CAR VALUE "C". 88 TYPE-HOME VALUE "H". 05 AMT-COV PIC 9(7)V99. 05 PREM-YR PIC 9(4)V99. FD PRINT-FILE DATA RECORD IS PRINTZ. 01 PRINTZ PIC X(80). Code TYPZ is a code with three possible valid characters: L, C and H. Processing will vary depending on what character is in this field. The level 88 allows me to assign a name to each of the valid characters. If TYPZ contains an L, then this condition is named TYPE-LIFE. If TYPZ contains a C, than this condition is named TYPE-CAR and if TYPZ contains an H, than this condition is named TYPE-HOME. The detail line contain the data that I want to write to the report is not set up in the FILE SECTION (it is set up in WORKING-STORAGE. Therefore, PRINTZ is simply given a picture of X(80).

3. WORKING-STORAGE SECTION. 01 INDICATORS. 05 MORE-RECS PIC XXX VALUE "YES". 88 END-OF-FILE VALUE "NO ". 01 WORK-AREAS. 05 PREM-MO-WS PIC 999V99 VALUE 0. 01 ACCUMULATORS. 05 TOT-MO-PREM-WS PIC 9(5)V99 VALUE 0. 01 PAGE-CONTROL. 05 PAGE-NO-WS PIC 99 VALUE 1. 05 LINE-CT-WS PIC 99 VALUE 0. 05 DATE-WS. 10 YR-WS PIC 99. 10 MO-WS PIC 99. 10 DA-WS PIC 99. Code MORE-RECS has a level 88 beneath it that defines the condition where MORE-RECS = “NO “. The name of that condition is END-OF-FILE. Note that you can still give a value to MORE-RECS when you are using level 88 condition names. PREM-MO-WS is a work area that will hold the result of the calculation to determine the premium. TOT-MO-PREM-WS is an accumulator that is added as the record are processed and printed on the total line when end of file is reached. PAGE-NO-WS is initialized at 1. It is moved to the header to print and is used to determine when to print the header on the first page. LINE-CT-WS is used to keep track of the number of lines on a page. In this program, when it passes 55 a new line is printed. DATE-WS is the date that is accepted from the system. It is then broken down into its parts - the first two characters are the year, the next two characters are the month and the final two characters are the day.

Code IDNO, NAMZ and AMT-COV are fields on the input. The data in these fields is moved to IDNO-PR, NAMZ-PR AND AMT- COV-PR. TYPZ-MSG-PR is determined by checking to see what character is contained in the input TYPZ field and moving an appropriate level to the line. The checking uses the level 88 condition names. PREM-MO-PR is the result of a calculation. The answer is stored in PREM-MO-WS and when the calculation is complete it is moved to PREM-MO-PR.

Code The date was brought in from the system and stored in WORKING-STORAGE. Now the components of the date are moved to the fields on the print line. Notice that the setup also puts a slash in between the month, day and year. The information on the column header is set up to align with the information in the columns. The PAGE-NO-WS is moved to PAGE-NO-HDR prior to writing the header.

As the records are processed, the calculated PREM-MO-WS is added to TOT-MO-PREM-WS. When end of file is reached and all records have been processed, PREM-MO-WS is moved to TOT- MO-PREM-TL and the total line is written.

ACCEPT is used to get data from outside the program. In this case, the program is getting the current date from the system. The reserve word for the system date is DATE. 01 INDICATORS. 05 MORE-RECS PIC XXX VALUE "YES". 88 END-OF-FILE VALUE "NO ". Note that END-OF-FILE is the condition name for MORE-RECS containing NO.

IF the first IF is true the action move “LIFE” is taken. If the first IF is not true then the ELSE is taken which asks the second IF. This continues through three Ifs. If all three Ifs are NO then the invalid message is moved to the line. This statement adds to the accumulator that will be moved to the final total line when processing is complete. This statement adds 1 to LINE-CT-WS which is tested at the top of the page to determine whether a new page should be started.

MOVE 4 TO LINE-CT-WS. C-100-TERMINATE. CLOSE INS-FILE PRINT-FILE. Code This routine sets up and writes the total line. The accumulator has been being added to as the processing was done. See the previous slide. When the code on the previous slide determines that the headers should be written, this routine is performed. The page number is moved to the line and the total lines are written. Then the page number is increased by 1 for the next time and the line count is reset to 4 because the header routine used 4 lines to write the headers.
