<snip> Of course, I am not a developer, so I may well be missing something. <snip> As a developer, I have to prepare for a client to run on various levels of the operating system. Some with some without using SMS management. Some are running JES3, most aren't. Some are using RACF some are using ACF2 some have their own home grown systems, so SAF doesn't solve it all. Some customers are running other ISV products that interfere with what the product I work on does. So to give you a fast answer about upper/lower, use CLIST over REXX, program in C/C++ or ALC, just doesn't cut it. JCL is a pain because JES3 expects one thing, JES2 allows another, the internal reader handles things differently (so if I want to submit from within a customizer job...). And then the idea that ISVs don't know SMP/E is a bit out there -- well I'd hope that ISVs know SMP/E. But the reason for autocurst was to allow the customer to immediately install AutoOPERATOR and then install the SMP/E stuff later (basically the system came "pre-installed" you loaded the SMP/E files/system later so you could put on maint). So there are lots of things that vendors have to take into consideration, and the biggest one today are the Sr. Systems Programmers who don't know what a USERMOD is or a JES exit.
