I think this may have been discussed before, but I just read (reread maybe) the article mentioned. Uhh, sure, let's take a 14 line job and change it to a 60+ line (without blank lines added for clarity) python script.
My eye caught this gem of a paragraph toward the end of the article. Now we have a reasonable replacement for our 14-line JCL. Our new Python version of the execution obviously uses more lines than JCL. These lines separate code from the input and data needed to run the code effectively. Additionally, the code checks input so the system doesn’t have to. Finally, it keeps people from the typos that happen when one modifies JCL prior to submission. This not only ensures that execution is less error free, but it also allows us to create a separation of concern with defaults set at configuration time and another set of options defined at execution time. "This not only ensures that execution is less error free". Hmm, Freudian slip here (?) but the double negative in there means the python script will introduce more errors into the execution.
