Of course, this discussion is not really about JCL, per se, but about the behavior of the START command. I'm reasonably sure that the START command is just building a new set of JCL that has an EXEC statement and the DD override, and has no idea of the actual contents of the PROC it's starting. All it knows is the proc name and the parameters you've provided on the command, and whether those parameters are DD parameters or not. Not knowing the actual PROC contents the START command has no way of reporting the conflict. I do agree that with the number of DD parameters that exist this can be confusing. Also, regarding picking a symbol name that IBM won't someday decide to use as a DD keyword: I think that if you use one of the 3 national characters ( $, #, or @) somewhere in your symbol name you'll be immune from future changes. IBM's internal programming and naming standards (at least as I understand them) prohibit us from using those characters in many situations, and JCL keywords should be one of them. (This is not an official IBM statement, however. It's just my personal observation.) -- Walt Farrell IBM STSM, z/OS Security Design ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
