Indeed! Yes, this I also see. Look at IBM tools and toys pages and other freebies to download to get an idea. Working with RACF/SMS/HSM/zOS/Automation/various languages/TSO/ISPF/REXX/Assembler/and more other things I find one interesting thing with Mainframes - You learn something new nearly everyday. For example, for one IBM-MAIN member, I confirmed a bug in ISMF earlier this year - a PTF was eventually made available. This is while I'm currently a RACF admin who was wearing a storage admin hat many centuries ago... In fact, I started with DOS, windoze and such animals on the 8086/80286/386 machines before I started with Mainframe, starting with VM+MVS/ESA and ending up with z/OS and all its goodies... Fact is - I see many IBM-MAIN members are having more experience than me and you... Just check their postings and CVs+websites... >Mainframe software systems seem to me to be like those layered liqueurs, they >keep adding a new color on top. It never ends. Cool! My auditors still can't believe that z/OS has so much security features - other platforms just don't have it. For them this is a new wild area, just like those sweets... ;-) I like their quote: 'Why is green screen so much secure than other platforms?'
