No particular goal in mind. Just learning. I already know REXX fairly well. Thanks.

I think I became competent. I also recommend z/OS Using REXX and z/OS UNIX System Services SA23-2283-40 Not shell, but enormously useful. Much of the power of the standard "C" library with the ease of coding Rexx. What's your goal; what would be your first practical/demo shell (or Rexx) program? In my earliest encounter with UNIX (Solaris) I was impressed by the significance of the "Uni" prefix; the ability to use a single language for terminal commands, scripting, and batch; as opposed to TSO, CLIST, Rexx, JCL, ... And the *uni*formity of shell's lexical analysis. Granted there are some commands you'd like to be peculiar; I find this outweighed by "everything works the same." Except for outliers such as "dd" (needlessly -- I suspect it was invented by an OS/360 partisan) and "find" (with better reason -- it's command line is somewhat like you'd expect of a DFSORT control flle). What's your goal? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
