  1. Submitting • Instructions on web site • CS 1024 students • Read guide • Download the EAGS Client Configuration Tool for Fall 1999 • Save as box • Save it somewhere • Start, run, browse, double click on it • Installs quickly • Go to C:\TEMP and run CuratorSetup.exe

  2. Now get the java runtime 1.2.2 • http://java.sun.com/products//jdk/1.2/jre/download-windows.html • US English version • One large bundle • Click on continue • Accept • Download from java.sun.com • http download • Save as, save • Start,run,browse, double click… • Go through the instructions • Now use the submit link • Association with data names

  3. Chapter 4 • COBOL notation • Syntax and notational conventions - optional, required,lower & upper case • Relevant to the book • Identification Division • Position in program • Purpose and syntax • provide identifying info - author,dates • division and up to 6 paragraphs • PROGRAM-ID & header are required • 5 others are optional

  4. Environment Division • CONFIGURATION SECTION (Optional Entries) • Identifies the computer • SOURCE-COMPUTER • OBJECT-COMPUTER • INPUT-OUTPUT SECTION • Associates the files in the program with the files known to the OS • FILE-CONTROL • SELECT statement • ASSIGN clause

  5. Data Division • FILE SELECTION • FD (File Description) statement • Size and type of each field • Order in which the fields appear • relationship of the fields • LABEL RECORDS statement (optional) • RECORD CONTAINS (record description) statement (optional) • DATA RECORD IS statement (optional) documentation only

  7. Data Division • PICTURE CLAUSE • PICTURE IS, PICTURE, PIC IS, PIC • Size • Number of characters, positions • Type • 9 - numeric, 0-9 • 999 same as 9(3) • Assumed decimal point • Use of a V, PIC 9V99 can hold 1.23 • X - alphanumeric, all characters including numbers as characters • XXXXXX same as X(6)

  10. Data Division • Level numbers • Describe the relationship between the fields in the record • Elementary Item - cannot be further divided • Group Item - can be further divided • Use 01 to 49 • 01 denotes a record as a whole • 02 -49 used for fields within a record • Elementry numbers must have picture clauses • groups cannot have picture clauses

  11. Data Division • WORKING-STORAGE SECTION • defines any data name that does not appear in a file • stores results of calculations, flags, switch control, constants • Used to define print lines • Intermediate data storage • Filler - can use as a field name, not referenced anywhere else • typically holds spaces or constants

  13. VALUE clause • initializes contents of a field (Literals) • Numeric literals , VALUE 3.00 • Non-numeric literals, VALUE ‘ENGINEERING’ • Figurative constants (zero or space), VALUE SPACES

  14. Figure 4.8 Development of a COBOL Program (Constants and Rates) 1. Calculate tuition due at the rate of $200 per credit.2. The union fee is $25.3. Compute the activity fee based on the number of credits taken; $25 for 6 credits or less, $50 for 7 to 12 credits, and $75 for more than 12 credits.4. Award a scholarship equal to the amount in the incoming record if, and only if, the GPA is greater than 2.5.
