DAT2330 - MVS Intro Homework (first class)
----------------------------
Ian D. Allen - idallen@ncf.ca

Read Chapters 1-4 in the OS/390 JCL text, with emphasis on the areas
mentioned in the chapter1-4.txt study guide.

These homework assignments prepare you for the tests.  I will review
the homework solutions in class each week.

Homework is not marked; however, a good mark in this section of the
course is unlikely if you don't do any.

Offline Exercise:

1)  Identify all the syntax errors in the JCL file "badjcl.txt".
    (In addition to syntax errors, there is one incorrectly spelled
    parameter and another incorrectly spelled parameter value.)

2)  Review the file "expljcl.txt".  Look up (in your textbook) and briefly
    give the purpose of each parameter on each statement in this job
    stream, using the given format.  These parameters are all frequently
    used JCL parameters, and all are covered in our work this term.

Online Exercise:

    Time yourself on how long it takes you to do this.

    Using VI, enter the 15 lines of JCL given in section 3.5.3 on page
    50/51 into a file on the Linux test machine that you will name:

       $HOME/jcl/clg.txt

    Do not copy the file from other students; type it in yourself.
    There are no marks for a right answer - this exercise is to help
    you know how accurate you are in typing JCL!

    The JCL must be entered exactly, including counting *spaces*!
    No blank lines are allowed.  All the lines start in column 1.
    Every space and comma is important.  Be *exact*!
    
    Note: Fix the syntax error on the last line (SPACE=) of Page 50.
    (The author made the same syntax error all through the chapter!)

Deliverables:

    I will collect the file $HOME/jcl/clg.txt from your home directories
    and send you a Unix "diff" listing comparing what you typed with
    the actual JCL, at the end of the week.  (If you spell the file name
    incorrectly, it won't be processed.)

Homework is not marked; however, a good mark in this section of the course
is unlikely if you don't do any.  We will review homework in class.
