JCL was designed for OS360 on a 256K real machine (the original design point for PCP was 64K). In addition, I suspect that the design was done by engineers or mathematicians for whom "not and" and "not or" were familiar concepts. Virtually all of the printers were upper case only and at least in my shop it was a struggle to get a printer that printed the special characters correctly (the 48 character train was adequate FSVO adequate). Lower case was out of the question. Memory and instruction cycles were at a premium. Even on a 1 megabyte mod 65 we were stingy about region sizes. While I share your (Paul's) distaste for JCL, the crime is that IBM hasn't provided a clear migration path for at least new things to either REXX or one of the shells. It also hasn't provided a migration path so that we could have longer member names, longer data set names and a generation data set facility for ESDS data sets. We are stuck on software architecture that was designed for the limitations of the original 360's using work arounds and kludges. It is for this reason that I am not optimistic about the long term viability of the z series and z/OS. > >-- gil > ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
