I smiled as I read this thread because it brought back memories for me. I was then at Sun Microsystems after the acquisition of STK. And one of the Solaris leads there explained to me that the reason the Mainframe was on its last legs was JCL. I just looked at him and told him to talk to me when he got a clue. I for one never viewed JCL as hard or even highly ridged. Not only did it seem like it could win a Rube Goldberg for making something simple overly complex. After a good head shake I decided I am glad I can retire at any moment I wish.

I'd run the assembler from TSO READY so I wouldn't have to wait for an initiator. My way of programming was always like starting with a ball of clay generally like what I wanted, then adding the details as I went along. That method means lots and lots of compiles. Then one day my supervisor dropped by my desk with a blue-bar listing titled, "Top 10 TSO CPU Users" and I think I was on the top. Oops.
