Introduction to COBOL - CIS12

Weekly Schedule

Week Information: Sample programs: Sample programs are available in two groups:
programs using screens used at the beginning of the semester and more traditional programs used later in the semester
Remember, 10% of your grade is strongly influenced by whether you get work in on time!
Programs: Unless specified differently on the program, programs are due in three weeks. When a program is passed in, it should include the logic flowchart, the rough code or notes that you made prior to writing the program, the program code and the output produced. For web students, the flowchart and rough code should be mailed, put under my door, or put in my box unless you have access to a scanner.
PowerPoint Presentations: Free PowerPoint viewer for 97,2000,2002 users
More information on downloads.
Note that the speaker notes are provided on a separate Word document if you are having trouble accessing them!

No new assignments - work on the program.
Contact me about the midsemester exam.
Week #10
Week of April 4th
Anyone who has completed the programs to avoid the midsemester by April 11th will get extra credit. I will accept these programs through April 11th to get out of the midsemester. Anyone who has not met the criteria by April 11th will have to take the midsemester (contact me via email for the exam). Students can choose to take the midsemester for extra credit. Ignore the dates inside the exam.
We are looking at edit programs. Again there are notes, examples and powerpoint presentations. Be sure to look at this program and this Presentation first: Sample edit program using screens being discussed - .html version

Week #8
Week of Match 21st
It is getting close to mid semester time. If by the first of April, you have finished the first two programs in programming assignment #1 (that means they are running and I have them) and finished programming assignment #2 which was assigned last week, you can opt not to take the mid-semester exam. In that case the 10% of the grade will be included in homework and programs. Email me or ask me in class if you have questions!
Please continue to review math statements and go over the handouts on math statements. Please continue to look at all the sample programs under IF statements and be sure you look at this handout: Math IF statements
Please make sure you have read all of the notes under IF conditions, level 88 and case structures - they are at the note section: scroll down for the notes on IF conditions, level 88 and case structures
Your should also look at the programs with level 88 and case structure - they are located at the second programs page: scroll down for the programs with level 88 and case structure
Also be sure to go to presentations and make sure you have read all of the presentations on IF statements, the second programming assignment and level 88s - they are with the information on notes: scroll down for the presentations under Topics - IF statements
You also need to look at the examples and presentations on screen processing. Under programs go to screen processing - cont. Under presentations go to More on screen processing. You will find the information about color for the screen in these examples.

Week #4
Week of February 14th
We are also going to look at the program to read a file called READ1 (it is located under sample programs in the category (looping, creating and reading with screens). We are also going to look at the programs under the category conditions and totals with screens. The programs have names like readif1 etc. They are located at the location for the new sample programs: Sample programs using screens
You should also read the notes on looping. It can be found on the home page for the course under New Introduction. Notes to read
Specifically the can be found at Notes on looping
Also read the notes on if statements - usually I cover these later in the course, but I have decided to cover them now while we are looking at screen programs - we will revisit them later. The notes are at Notes on IF statments
The IF statement notes will be covered next week.
Assignment to be passed in:
Second half of programming assignment #1 Due in two weeks
Second data editing assignment
Week #3
Week of February 7th
We are going to continue to look at the math, numeric data and the compute statement that we started last week. If you have not looked at the notes and the sample programs, look at the things I asked you to read last week.
Please read the following notes on loops and files and check the program examples that it discusses.
Notes on looping examples: ADDDALP.CBL, CREATE1.CBL, READ1.CBL. The examples are under Sample Programs for CIS12: Programs to look at.
Please look at the accompanying slide show presentation (note you should read the notes and look at the presentation because they convey different information!).
Loops in COBOL screen programs
    Separate speaker notes to accompany Loops in COBOL screen programs
Remember, if you have a text book it is a great reference and you can check the topics being covered in the text book.
Note about editing: If data is being read from a file, you do not have an actual decimal point. However, if the user is inputing data on the screen then they should type in the decimal place to conform to the V in the input picture.
Assignment to be passed in:
First data editing/formatting assignment
First math assignment
First half of programming assignment #1
Note: On the file layout there is nothing for characters 27 through 40. These characters must be accounted for so when you are describing the file you should include an 05 FILLER with a picture that covers characters 27 through 40. Next week when you read this file, you need to have the same file description.
Week #2
Week of January 31st
Please look at the following PowerPoint Presentations:
Display/Accept program with Add
    Separate speaker notes to accompany Display/Accept program with Add - ADDDA.CBL
