I think much of the disdain for JCL comes from inaccurate expectations set by calling it a “language”. JCL is *not a programming language*. It’s not even a minimal scripting language. It’s the punch-card-technology equivalent of gestures like double-clicking an app icon or selecting “open” from a file menu in a modern GUI. Yes, it’s far from perfect. The condition code thing is pretty goofy (although you’ve been able to use IF constructs instead for over two decades) and a lot of keywords and values are pretty obscure. But for what it was actually designed to do, it works pretty well. -- Curtis Pew ([email protected]) ITS Systems Core The University of Texas at Austin ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
