    More Detail::: What SUBMIT Does with Each LJL Statement:

    For every statement, SUBMIT generates corresponding commands in the .deck file. Below is a step-by-step breakdown:

    One //jo line, as many /dd lines as are required, and as many //ex as are required

    //jo sumjob [email protected] log=print class=a

    • Generates a deck command to invoke ifclass a, which checks if the job’s class allows execution at run time.

    • Generates a deck command to Log “sumjob is starting” to /var/log/JCL/ with a timestamp.

    • Generates a deck command to create /tmp/sumjob

    • Generates a deck command to initializes /tmp/sumjob/jobname.log with a formatted header (e.g., via figlet sumjob).

    Job Classes: A = Runs as soon as submitted B = Runs only if load is low enough C = Runs in Off-Hours

    //dd alias source(here|file=pathandfilename|new) disp(keep|scratch)

    • Note the disp (disposition) if keep the put the file in /home/user/.lcl/jobname as whatever the alias is if the disp(scratch) then the file will go into the /tmp/jobname directory as named by the alias.

    • Generate deck commands to

    – if source is here: copy lines from lcl up to ‘/*’ to the deck file as a here document if source is a file: add commands to copy the file into a working directory either in user’s home or in the tmp directory under the alias. //dd users source(file=/etc/passwd) disp(keep) ==> copy /etc/passwd to /home/user/.ljl/users

    //ex somecommand --options < alias

    -Generate doc commands to execute the program as specified and save the output to the logfile In this case echo (somecommand --options < aliasproperlyexpanded ) > logfile

    The deck file now forms a fully functional batch file to do the specified computation.

    I manually created a .deck file to compile and run a Fortran program with specific data and to create a .log file of all the output, the Fortran program, and the data. I found it to be picky and somewhat hard. So I thought to myself: With something like JCL, one could take simple JCL-like statements, here documents for the source and data files, and programmatically combine them to make a script like the one I created manually.

    t+ and T- to upstream neighbor (2) + a single wire from upstream to tell you to send (3), R+ and R- (5) to down stream neighbor + a single wire to let downstream know when you can receive from them.(6) And a pair to control a relay in what would be like a token ring MAU. Token ring is also a logical ring and a physical star: All the physical cables come to a central hub (physical star) but the machines are connected

    Logical Ring                                                       Physical Star
+-->[ r t ]--> [r  t] -->[ r  t ]--> [r  t] --> [ r t]--+       [ machine1 ] ===== cat 6 ==== |  mau |=====cat6== [ machine 3 ]
 |                                                                 |       [ machine2 ]====== cat 6 ====|          |====cat 6 == [ machine 4 ]
+-----------------------------------------------------+

    until the last machine loops around to connect to the first.

    Is it anything like token ring? No, The difference is no token to lose, No ring master or deputy ring master to lead things- everyone just plays along according to basic rules. Any machine can move data to it’s upstream neigbor at any time that neighbor is ready to take it, no one machine at a time getting to talk. So it’s not like token ring. Also unlike Ethernet, you can connect any number of machines in a ring: 5 for a small office, 20 for a department of a large firm, 200 for every employee of a firm, 2000 for all the offices of a company or a part of a neighborhood. Since machines are not contending for bandwidth there is no collision, no backdown and resend.

    Rings of machines are connected to bigger rings via gateways - which also have their own way of assigning addresses to each of their ports.
