Indeed. The tiny improvements in JCL over time make me think that POK

broke production jobs would be Bad, but that's what testing and ESPs

always astonished (and a bit depressed).
I suspect the problem with JCL is that the base code was laid down about
fifty years ago. I remember seeing eye catchers with 1968 dates in the
late 1990's. At that time (1960's) I doubt that the developers had the
rigourous "documentation" requirements of even yesteryear much less
recent years. So I think that to days developers are as much in the dark
about the code as you and I.
Possibly someone out there who kept the source tapes (Seymour Metz (I
apologize in advance about name spelling) could comment about code
quality. And I must say that quality expectation between "1970" and
"2010" are vastly different
